There are common cases where copy_file_range can noisily
log "source and target of copy not on same server"
e.g. the mv command across mounts to two different server's shares.
Change this to informational rather than logging as an error.
A followon patch will add dynamic trace points e.g. for
cifs_file_copychunk_range

The congestion_count was introduced into the struct cgroup by
commit d09d8df3a294 ("blkcg: add generic throttling mechanism"),
but since it is closely related to the blkio subsys, it is not
appropriate to put it in the struct cgroup, so let's move it to
struct blkcg. There should be no functional changes because blkcg
is per cgroup.

Configuration for sbq:
depth=64, wake_batch=6, shift=6, map_nr=1
1. There are 64 requests in progress:
map->word = 0xFFFFFFFFFFFFFFFF
2. After all the 64 requests complete, and no more requests come:
map->word = 0xFFFFFFFFFFFFFFFF, map->cleared = 0xFFFFFFFFFFFFFFFF
3. Now two tasks try to allocate requests:
T1: T2:
__blk_mq_get_tag .
__sbitmap_queue_get .
sbitmap_get .
sbitmap_find_bit .
sbitmap_find_bit_in_word .
__sbitmap_get_word -> nr=-1 __blk_mq_get_tag
sbitmap_deferred_clear __sbitmap_queue_get
/* map->cleared=0xFFFFFFFFFFFFFFFF */ sbitmap_find_bit
if (!READ_ONCE(map->cleared)) sbitmap_find_bit_in_word
return false; __sbitmap_get_word -> nr=-1
mask = xchg(&map->cleared, 0) sbitmap_deferred_clear
atomic_long_andnot() /* map->cleared=0 */
if (!(map->cleared))
return false;
/*
* map->cleared is cleared by T1
* T2 fail to acquire the tag
*/
4. T2 is the sole tag waiter. When T1 puts the tag, T2 cannot be woken
up due to the wake_batch being set at 6. If no more requests come, T1
will wait here indefinitely.
This patch achieves two purposes:
1. Check on ->cleared and update on both ->cleared and ->word need to
be done atomically, and using spinlock could be the simplest solution.
2. Add extra check in sbitmap_deferred_clear(), to identify whether
->word has free bits.
Fixes: ea86ea2cdced ("sbitmap: ammortize cost of clearing bits")

This patch adds a poll queue check, aiming to help users use polled IO
accurately.
If users do polled IO but the device doesn't have poll queues, they will
get suboptimal performance data and waste CPU resources. Add a poll queue
check batching this. If users don't have the device properly configured,
or if it simply doesn't support polled IO, it will error the IO with
-EOPNOTSUPP. This is similar to what we used to do for sync polled IO,
which is no longer supported.

Currently the BTRFS_MOUNT_* flags are already beyond 32 bits, this is
going to cause compilation errors for some 32 bit systems, as their
unsigned long is only 32 bits long, thus flag
BTRFS_MOUNT_IGNORESUPERFLAGS overflows and can lead to errors.
Fix the problem by:
- Migrate all existing BTRFS_MOUNT_* flags to unsigned long long
- Migrate all mount option related variables to unsigned long long
* btrfs_fs_info::mount_opt
* btrfs_fs_context::mount_opt
* mount_opt parameter of btrfs_check_options()
* old_opts parameter of btrfs_remount_begin()
* old_opts parameter of btrfs_remount_cleanup()
* mount_opt parameter of btrfs_check_mountopts_zoned()
* mount_opt and opt parameters of check_ro_option()

- Rename find_resource() to find_resource_space() to make it more
descriptive for exporting outside resource.c (Ilpo Järvinen)
- Document find_resource_space() and the resource_constraint struct it uses
(Ilpo Järvinen)
- Add typedef resource_alignf to make it simpler to declare allocation
constraint alignf callbacks (Ilpo Järvinen)
- Open-code the no-constraint simple alignment case to make the
simple_align_resource() default callback unnecessary (Ilpo Järvinen)
- Export find_resource_space() because PCI bridge window allocation needs
to learn whether there's space for a window (Ilpo Järvinen)
- Fix a double-counting problem in PCI calculate_memsize() that led to
allocating larger windows each time a bus was removed and rescanned (Ilpo
Järvinen)
- When we don't have space to allocate larger bridge windows, allocate
windows only large enough for the downstream devices to prevent cases
where a device worked originally, but not after being removed and
re-added (Ilpo Järvinen)
* pci/resource:
PCI: Relax bridge window tail sizing rules
PCI: Make minimum bridge window alignment reference more obvious
PCI: Fix resource double counting on remove & rescan
resource: Export find_resource_space()
resource: Handle simple alignment inside __find_resource_space()
resource: Use typedef for alignf callback
resource: Document find_resource_space() and resource_constraint
resource: Rename find_resource() to find_resource_space()

- Warn about doing a Secondary Bus Reset without holding the device lock
(Dan Williams)
- Lock bridge in addition to downstream hierarchy before doing a Secondary
Bus Reset (Dan Williams)
* pci/reset:
PCI: Add missing bridge lock to pci_bus_lock()
PCI: Warn on missing cfg_access_lock during secondary bus reset

- Detect if a device was removed or replaced during system sleep so we
don't assume a new device is the one that used to be there. This uses
Vendor/Device/Subsystem/Class/Revision and Device Serial Number (if
implemented), so it's not fool-proof and drivers may know how to detect
more cases (Lukas Wunner)
- Add missing MODULE_DESCRIPTION() macro (Jeff Johnson)
* pci/hotplug:
PCI: acpiphp: Add missing MODULE_DESCRIPTION() macro
PCI: pciehp: Detect device replacement during system sleep

- Disable AER and DPC during suspend so that if they share an interrupt
with PME and errors occur during suspend, the AER or DPC interrupt
doesn't cause spurious wakeups (Kai-Heng Feng)
* pci/err:
PCI/DPC: Disable DPC service on suspend
PCI/AER: Disable AER service on suspend

- Move the PRESERVE_BOOT_CONFIG ACPI _DSM evaluation from drivers/acpi to
drivers/pci so we can unify with similar DT functionality (Vidya Sagar)
- Add of_pci_preserve_config() to check for a DT "linux,pci-probe-only"
property on a per-host bridge basis in addition to a global basis (Vidya
Sagar)
- Unify ACPI PRESERVE_BOOT_CONFIG _DSM and DT "linux,pci-probe-only" in a
generic pci_preserve_config() path (Vidya Sagar)
* pci/enumeration:
PCI: Use preserve_config in place of pci_flags
PCI: Unify ACPI and DT 'preserve config' support
PCI: of: Add of_pci_preserve_config() for per-host bridge support
PCI: Move PRESERVE_BOOT_CONFIG _DSM evaluation to pci_register_host_bridge()

- If there's a device below a bridge, prevent a use-after-free by holding a
reference to the device while waiting for the secondary bus to be ready
in case the device is concurrently removed, e.g., by DPC (Lukas Wunner)
* pci/dpc:
PCI/DPC: Fix use-after-free on concurrent DPC and hot-removal

pcim_remove_mapping_from_legacy_table() helper functions to simplify
devres iomap table (Philipp Stanner)
- Reimplement devres that take a bit mask of BARs in a way that can be used
to map partial BARs as well as entire BARs (Philipp Stanner)
- Deprecate pcim_iomap_table() and pcim_iomap_regions_request_all() in
favor of pcim_* request plus pcim_* mapping (Philipp Stanner)

(Philipp Stanner)
- Use the existing pci_is_enabled() interface to replace the struct
devres.enabled bit (Philipp Stanner)
- Move the struct pci_devres.pinned bit to struct pci_dev (Philipp Stanner)
- Reimplement pcim_set_mwi() so it uses its own devres cleanup callback
instead of a special-purpose bit in struct pci_devres (Philipp Stanner)
- Add pcim_intx(), which is unambiguously managed, unlike pci_intx(), which
is managed if pcim_enable_device() has been called but unmanaged
otherwise (Philipp Stanner)

of pcim_set_mwi() and pci_intx() (Philipp Stanner)
- Add pcim_iomap_range(), a managed interface to map part of a BAR (Philipp
Stanner)
- Fix vboxvideo leak by using the new pcim_iomap_range() instead of the
unmanaged pci_iomap_range() (Philipp Stanner)
* pci/devres:
drm/vboxvideo: fix mapping leaks
PCI: Add managed pcim_iomap_range()
PCI: Remove legacy pcim_release()
PCI: Add managed pcim_intx()

- Add ACS quirk for Broadcom BCM5760X NIC, which doesn't allow peer-to-peer
transactions between functions, but doesn't advertise ACS support (Ajit
Khaparde)
- Add "pci=config_acs=" kernel command-line parameter to relax default ACS
settings to enable peer-to-peer configurations. Requires expert
knowledge of topology and ACS operation (Vidya Sagar)
