When add one disk to array, the md_reap_sync_thread is responsible
to activate the spare and set In_sync flag for the new member in
spare_active().
But if raid1 has one member disk A, and disk B is added to the array.
Then we offline A before all the datas are synchronized from A to B,
obviously B doesn't have the latest data as A, but B is still marked
with In_sync flag.
So let's not call spare_active under the condition, otherwise B is
still showed with 'U' state which is not correct.

When a disk is added to array, the following path is called in mdadm.
Manage_subdevs -> sysfs_freeze_array
-> Manage_add
-> sysfs_set_str(&info, NULL, "sync_action","idle")
Then from kernel side, Manage_add invokes the path (add_new_disk ->
validate_super = super_1_validate) to set In_sync flag.
Since In_sync means "device is in_sync with rest of array", and the new
added disk need to resync thread to help the synchronization of data.
And md_reap_sync_thread would call spare_active to set In_sync for the
new added disk finally. So don't set In_sync if array is in frozen.

When the 'last' device in a RAID1 or RAID10 reports an error,
we do not mark it as failed. This would serve little purpose
as there is no risk of losing data beyond that which is obviously
lost (as there is with RAID5), and there could be other sectors
on the device which are readable, and only readable from this device.
This in general this maximises access to data.
However the current implementation also stops an admin from removing
the last device by direct action. This is rarely useful, but in many
case is not harmful and can make automation easier by removing special
cases.
Also, if an attempt to write metadata fails the device must be marked
as faulty, else an infinite loop will result, attempting to update
the metadata on all non-faulty devices.
So add 'fail_last_dev' member to 'struct mddev', then we can bypasses
the 'last disk' checks for RAID1 and RAID10, and control the behavior
per array by change sysfs node.

Just like raid1, we do not queue write error bio to retry write

When write bio return error, it would be added to conf->retry_list
and wait for raid1d thread to retry write and acknowledge badblocks.
In narrow_write_error(), the error bio will be split in the unit of
badblock shift (such as one sector) and raid1d thread issues them
one by one. Until all of the splited bio has finished, raid1d thread
can go on processing other things, which is time consuming.
But, there is a scene for error handling that is not necessary.
When the device has been set faulty, flush_bio_list() may end
bios in pending_bio_list with error status. Since these bios
has not been issued to the device actually, error handlding to
retry write and acknowledge badblocks make no sense.
Even without that scene, when the device is faulty, badblocks info
can not be written out to the device. Thus, we also no need to
handle the error IO.

7471fb77ce4d ("md/raid6: Fix anomily when recovering a single device in
RAID6.") avoids rereading P when it can be computed from other members.
However, this misses the chance to re-write the right data to P. This
patch sets R5_ReadError if the re-read fails.
Also, when re-read is skipped, we also missed the chance to reset
rdev->read_errors to 0. It can fail the disk when there are many read
errors on P member disk (other disks don't have read error)
V2: upper layer read request don't read parity/Q data. So there is no
need to consider such situation.

Spread queues among present CPUs first, then building mapping on other
non-present CPUs.
So we can minimize count of dead queues which are mapped by un-present
CPUs only. Then bad IO performance can be avoided by unbalanced mapping
between present CPUs and queues.
The similar policy has been applied on Managed IRQ affinity.

Implement .cleanup_rq() callback for freeing driver private part

SCSI maintains its own driver private data hooked off of each SCSI
request, and the pridate data won't be freed after scsi_queue_rq()
returns BLK_STS_RESOURCE or BLK_STS_DEV_RESOURCE. An upper layer driver
(e.g. dm-rq) may need to retry these SCSI requests, before SCSI has
fully dispatched them, due to a lower level SCSI driver's resource
limitation identified in scsi_queue_rq(). Currently SCSI's per-request
private data is leaked when the upper layer driver (dm-rq) frees and
then retries these requests in response to BLK_STS_RESOURCE or
BLK_STS_DEV_RESOURCE returns from scsi_queue_rq().
This usecase is so specialized that it doesn't warrant training an
existing blk-mq interface (e.g. blk_mq_free_request) to allow SCSI to
account for freeing its driver private data -- doing so would add an
extra branch for handling a special case that all other consumers of
SCSI (and blk-mq) won't ever need to worry about.
So the most pragmatic way forward is to delegate freeing SCSI driver
private data to the upper layer driver (dm-rq). Do so by adding
new .cleanup_rq callback and calling a new blk_mq_cleanup_rq() method
from dm-rq. A following commit will implement the .cleanup_rq() hook
in scsi_mq_ops.

device zone reset operations where we just simply issue bio with the
newly introduced req op.
We issue this req op when the number of sectors is equal to the device's
partition's number of sectors and device has no partitions.
We also add support so that blk_op_str() can print the new reset-all

This patch also adds a generic make request check for newly

Consider the following example:
* The logical block size is 4 KB.
* The physical block size is 8 KB.
* max_sectors equals (16 KB >> 9) sectors.
* A non-aligned 4 KB and an aligned 64 KB bio are merged into a single
non-aligned 68 KB bio.
The current behavior is to split such a bio into (16 KB + 16 KB + 16 KB
+ 16 KB + 4 KB). The start of none of these five bio's is aligned to a
physical block boundary.
This patch ensures that such a bio is split into four aligned and
one non-aligned bio instead of being split into five non-aligned bios.
This improves performance because most block devices can handle aligned
requests faster than non-aligned requests.
Since the physical block size is larger than or equal to the logical
block size, this patch preserves the guarantee that the returned
value is a multiple of the logical block size.

blk-mq may schedule to call queue's complete function on remote CPU via
IPI, but doesn't provide any way to synchronize the request's complete
fn. The current queue freeze interface can't provide the synchonization
because aborted requests stay at blk-mq queues during EH.
In some driver's EH(such as NVMe), hardware queue's resource may be freed &
re-allocated. If the completed request's complete fn is run finally after the
hardware queue's resource is released, kernel crash will be triggered.
Prepare for fixing this kind of issue by introducing
blk_mq_tagset_wait_completed_request().

This bug manifests itself because the SYMBOL_WRITTEN flag is never

"A series of commits to deal with the regression caused by the generic
VDSO implementation.
The usage of clock_gettime64() for 32bit compat fallback syscalls
caused seccomp filters to kill innocent processes because they only
allow clock_gettime().
Handle the compat syscalls with clock_gettime() as before, which is
not a functional problem for the VDSO as the legacy compat application
interface is not y2038 safe anyway. It's just extra fallback code
which needs to be implemented on every architecture.
It's opt in for now so that it does not break the compile of already
converted architectures in linux-next. Once these are fixed, the
#ifdeffery goes away.
So much for trying to be smart and reuse code..."

Pull RISC-V fixes from Paul Walmsley:
"Three minor RISC-V-related changes for v5.3-rc3:
- Add build ID to VDSO builds to avoid a double-free in perf when
libelf isn't used
- Align the RV64 defconfig to the output of "make savedefconfig" so
subsequent defconfig patches don't get out of hand
- Drop a superfluous DT property from the FU540 SoC DT data (since it
must be already set in board data that includes it)"
* tag 'riscv/for-v5.3-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux:
riscv: defconfig: align RV64 defconfig to the output of "make savedefconfig"
riscv: dts: fu540-c000: drop "timebase-frequency"
riscv: Fix perf record without libelf support
