I've been timing various fuse operations and it's quite annoying to do
with kprobes. Add two tracepoints for sending and ending fuse requests
to make it easier to debug and time various operations.

fuse_writepage_locked()
This change refactors the shared logic in fuse_writepages_fill() and
fuse_writepages_locked() into two separate helper functions,
fuse_writepage_args_page_fill() and fuse_writepage_args_setup().

Before this change, wpa->ia.ff is initialized with an acquired reference
on the fuse file right before it submits the writeback request. If there
are auxiliary writebacks, then the initialization and reference
acquisition needs to also be set before we submit the auxiliary writeback
request.
To make the logic simpler and to pave the way for a subsequent
refactoring of fuse_writepages_fill() and fuse_writepage_locked(), this
change initializes and acquires wpa->ia.ff when the wpa is allocated.

To pave the way for refactoring out the shared logic in
fuse_writepages_fill() and fuse_writepage_locked(), this change converts
the temporary page in fuse_writepages_fill() to use the folio API.
This is similar to the change in commit e0887e095a80 ("fuse: Convert
fuse_writepage_locked to take a folio"), which converted the tmp page in
fuse_writepage_locked() to use the folio API.
inc_node_page_state() is intentionally preserved here instead of
converting to node_stat_add_folio() since it is updating the stat of the
underlying page and to better maintain API symmetry with
dec_node_page_stat() in fuse_writepage_finish_stat().

callback
Prior to this change, data->ff is checked and if not initialized then
initialized in the fuse_writepages_fill() callback, which gets called
for every dirty page in the address space mapping.
This logic is better placed in the main fuse_writepages() caller where
data.ff is initialized before walking the dirty pages.

In some cases, the fi->writepages may be empty. And there is no need
to check fi->writepages with spin_lock, which may have an impact on
performance due to lock contention. For example, in scenarios where
multiple readers read the same file without any writers, or where
the page cache is not enabled.

Virtiofs has its own queuing mechanism, but still requests are first queued
on fiq->pending to be immediately dequeued and queued onto the virtio

The queuing on fiq->pending is unnecessary and might even have some

It seems only a relict: in a Linux 2.6.11-rc2 patch [1] the
linux/types.h include was unexplainedly changed to a linux/posix_types.h
include. I can only assume it was just an error. Finally headers_check
complained "found __[us]{8,16,32,64} type without #include
<linux/types.h>" and commit ae612fb05b0f ("headers_check fix: mips,

remove the posix_types.h include.

====================
mptcp: more fixes for the in-kernel PM
Here is a new batch of fixes for the MPTCP in-kernel path-manager:
Patch 1 ensures the address ID is set to 0 when the path-manager sends
an ADD_ADDR for the address of the initial subflow. The same fix is
applied when a new subflow is created re-using this special address. A
fix for v6.0.
Patch 2 is similar, but for the case where an endpoint is removed: if
this endpoint was used for the initial address, it is important to send
a RM_ADDR with this ID set to 0, and look for existing subflows with the
ID set to 0. A fix for v6.0 as well.
Patch 3 validates the two previous patches.
Patch 4 makes the PM selecting an "active" path to send an address
notification in an ACK, instead of taking the first path in the list. A
fix for v5.11.
Patch 5 fixes skipping the establishment of a new subflow if a previous
subflow using the same pair of addresses is being closed. A fix for
v5.13.
Patch 6 resets the ID linked to the initial subflow when the linked
endpoint is re-added, possibly with a different ID. A fix for v6.0.
Patch 7 validates the three previous patches.
Patch 8 is a small fix for the MPTCP Join selftest, when being used with
older subflows not supporting all MIB counters. A fix for a commit
introduced in v6.4, but backported up to v5.10.
Patch 9 avoids the PM to try to close the initial subflow multiple
times, and increment counters while nothing happened. A fix for v5.10.
Patch 10 stops incrementing local_addr_used and add_addr_accepted
counters when dealing with the address ID 0, because these counters are
not taking into account the initial subflow, and are then not
decremented when the linked addresses are removed. A fix for v6.0.
Patch 11 validates the previous patch.
Patch 12 avoids the PM to send multiple SUB_CLOSED events for the
initial subflow. A fix for v5.12.
Patch 13 validates the previous patch.
Patch 14 stops treating the ADD_ADDR 0 as a new address, and accepts it
in order to re-create the initial subflow if it has been closed, even if
the limit for *new* addresses -- not taking into account the address of
the initial subflow -- has been reached. A fix for v5.10.
Patch 15 validates the previous patch.

This test extends "delete re-add signal" to validate the previous
commit: when the 'signal' endpoint linked to the initial subflow (ID 0)
is re-added multiple times, it will re-send the ADD_ADDR with id 0. The
client should still be able to re-create this subflow, even if the
add_addr_accepted limit has been reached as this special address is not
considered as a new address.
The 'Fixes' tag here below is the same as the one from the previous
commit: this patch here is not fixing anything wrong in the selftests,
but it validates the previous fix for an issue introduced by this commit
ID.

The ADD_ADDR 0 with the address from the initial subflow should not be
considered as a new address: this is not something new. If the host
receives it, it simply means that the address is available again.
When receiving an ADD_ADDR for the ID 0, the PM already doesn't consider
it as new by not incrementing the 'add_addr_accepted' counter. But the
'accept_addr' might not be set if the limit has already been reached:
this can be bypassed in this case. But before, it is important to check
that this ADD_ADDR for the ID 0 is for the same address as the initial
subflow. If not, it is not something that should happen, and the
ADD_ADDR can be ignored.
Note that if an ADD_ADDR is received while there is already a subflow
opened using the same address, this ADD_ADDR is ignored as well. It
means that if multiple ADD_ADDR for ID 0 are received, there will not be
any duplicated subflows created by the client.

The initial subflow might have already been closed, but still in the
connection list. When the worker is instructed to close the subflows
that have been marked as closed, it might then try to close the initial
subflow again.
A consequence of that is that the SUB_CLOSED event can be seen twice:
# ip mptcp endpoint
1.1.1.1 id 1 subflow dev eth0
2.2.2.2 id 2 subflow dev eth1
# ip mptcp monitor &
[ CREATED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9
[ ESTABLISHED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9
[ SF_ESTABLISHED] remid=0 locid=2 saddr4=2.2.2.2 daddr4=9.9.9.9
# ip mptcp endpoint delete id 1
[ SF_CLOSED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9
[ SF_CLOSED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9
The first one is coming from mptcp_pm_nl_rm_subflow_received(), and the
second one from __mptcp_close_subflow().
To avoid doing the post-closed processing twice, the subflow is now
marked as closed the first time.
Note that it is not enough to check if we are dealing with the first
subflow and check its sk_state: the subflow might have been reset or
closed before calling mptcp_close_ssk().

'local_addr_used' and 'add_addr_accepted' are decremented for addresses
not related to the initial subflow (ID0), because the source and
destination addresses of the initial subflows are known from the
beginning: they don't count as "additional local address being used" or
"ADD_ADDR being accepted".
It is then required not to increment them when the entrypoint used by
the initial subflow is removed and re-added during a connection. Without
this modification, this entrypoint cannot be removed and re-added more
than once.

The initial subflow has a special local ID: 0. It is specific per
connection.
When a global endpoint is deleted and re-added later, it can have a
different ID, but the kernel should still use the ID 0 if it corresponds
to the initial address.
This test validates this behaviour: the endpoint linked to the initial
subflow is removed, and re-added with a different ID.
Note that removing the initial subflow will not decrement the 'subflows'
counters, which corresponds to the *additional* subflows. On the other
hand, when the same endpoint is re-added, it will increment this
counter, as it will be seen as an additional subflow this time.

The initial subflow has a special local ID: 0. It is specific per
connection.
When a global endpoint is deleted and re-added later, it can have a
different ID -- most services managing the endpoints automatically don't
force the ID to be the same as before. It is then important to track
these modifications to be consistent with the ID being used for the
address used by the initial subflow, not to confuse the other peer or to
send the ID 0 for the wrong address.
Now when removing an endpoint, msk->mpc_endpoint_id is reset if it
corresponds to this endpoint. When adding a new endpoint, the same
variable is updated if the address match the one of the initial subflow.

The lookup_subflow_by_daddr() helper checks if there is already a
subflow connected to this address. But there could be a subflow that is
closing, but taking time due to some reasons: latency, losses, data to
process, etc.
If an ADD_ADDR is received while the endpoint is being closed, it is
better to try connecting to it, instead of rejecting it: the peer which
has sent the ADD_ADDR will not be notified that the ADD_ADDR has been
rejected for this reason, and the expected subflow will not be created
at the end.
This helper should then only look for subflows that are established, or
going to be, but not the ones being closed.

The initial subflow has a special local ID: 0. When an endpoint is being
deleted, it is then important to check if its address is not linked to
the initial subflow to send the right ID.
If there was an endpoint linked to the initial subflow, msk's
mpc_endpoint_id field will be set. We can then use this info when an
endpoint is being removed to see if it is linked to the initial subflow.
So now, the correct IDs are passed to mptcp_pm_nl_rm_addr_or_subflow(),
it is no longer needed to use mptcp_local_id_match().

When the endpoint used by the initial subflow is removed and re-added
later, the PM has to force the ID 0, it is a special case imposed by the
MPTCP specs.
Note that the endpoint should then need to be re-added reusing the same
ID.

Largely inspired from hid_bpf.c for the fixture setup.
Create a couple of tests for hidraw:
- create a uhid device and check if the fixture is working properly
- inject one uhid event and read it through hidraw
These tests are not that useful for now, but will be once we start adding
the ioctl and BPFs to revoke the hidraw node.

When adding new tests programs, we need the same mechanics to create
new virtual devices, and read from their matching hidraw node.
Extract the common part into its own header so we can easily add new
tests C-files.

There is a need for userspace applications to open HID devices directly.
Use-cases include configuration of gaming mice or direct access to
joystick devices. The latter is currently handled by the uaccess tag in
systemd, other devices include more custom/local configurations or just
sudo.
A better approach is what we already have for evdev devices: give the
application a file descriptor and revoke it when it may no longer access
that device.
This patch is the hidraw equivalent to the EVIOCREVOKE ioctl, see
commit c7dc65737c9a ("Input: evdev - add EVIOCREVOKE ioctl") for full
details.
