When testing pnfs layout, nfsd got error NFS4ERR_SEQ_MISORDERED. It is caused by nfs return NFS4ERR_DELAY before validate_seqid(), don't update the sequnce id, but nfsd updates the sequnce id !!! According to RFC5661 20.9.3, " If CB_SEQUENCE returns an error, then the state of the slot (sequence ID, cached reply) MUST NOT change.

Problem: When an operation like WRITE receives a BAD_STATEID, even though recovery code clears the RECLAIM_NOGRACE recovery flag before recovering the open state, because of clearing delegation state for the associated inode, nfs_inode_find_state_and_recover() gets called and it makes the same state with RECLAIM_NOGRACE flag again. As a results, when we restart looking over the open states, we end up in the infinite loop instead of breaking out in the next test of state flags. Solution: unset the RECLAIM_NOGRACE set because of calling of nfs_inode_find_state_and_recover() after returning from calling recover_open() function.

Pull vfs fix from Al Viro: "Off-by-one in d_walk()/__dentry_kill() race fix. It's very hard to hit; possible in the same conditions as the original bug, except that you need the skipped branch to contain all the remaining evictables, so that the d_walk()-calling loop in d_invalidate() decides there's nothing more to do and doesn't go for another pass - otherwise that next pass will sweep the sucker.

Pull PCI / ACPI fix from Rafael Wysocki: "This fixes a bug uncovered by a recent driver core change that modified the implementation of the ACPI_COMPANION_SET() macro to strictly rely on its second argument to be either NULL or a valid pointer to struct acpi_device. As it turns out, pcibios_root_bridge_prepare() on x86 and ia64 works with the assumption that the only code path calling pci_create_root_bus() is pci_acpi_scan_root() and therefore the sysdata argument passed to it will always match the expectations of pcibios_root_bridge_prepare(). That need not be the case, however, and in particular it is not the case for the Xen pcifront driver that passes a pointer to its own private data strcture as sysdata to pci_scan_bus_parented() which then passes it to pci_create_root_bus() and it ends up being used incorrectly by pcibios_root_bridge_prepare()" * tag 'acpi-pci-4.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PCI / ACPI: Do not set ACPI companions for host bridges with parents

dm_merge_bvec() was originally added in f6fccb ("dm: introduce merge_bvec_fn"). In that commit a value in sectors is converted to bytes using << 9, and then assigned to an int. This code made assumptions about the value of BIO_MAX_SECTORS. A later commit 148e51 ("dm: improve documentation and code clarity in dm_merge_bvec") was meant to have no functional change but it removed the use of BIO_MAX_SECTORS in favor of using queue_max_sectors(). At this point the cast from sector_t to int resulted in a zero value. The fallout being dm_merge_bvec() would only allow a single page to be added to a bio. This interim fix is minimal for the benefit of stable@ because the more comprehensive cleanup of passing a sector_t to all DM targets' merge function will impact quite a few DM targets.

When stacking request-based dm device on non blk-mq device and device-mapper target could not map the request (error target is used, multipath target with all paths down, etc), the WARN_ON_ONCE() in free_rq_clone() will trigger when it shouldn't. The warning was added by commit aa6df8dd ("dm: fix free_rq_clone() NULL pointer when requeueing unmapped request"). But free_rq_clone() with clone->q == NULL is valid usage for the case where dm_kill_unmapped_request() initiates request cleanup. Fix this false warning by just removing the WARN_ON -- it only generated false positives and was never useful in catching the intended case (completing clone request not being mapped e.g. clone->q being NULL).

The commit [49fb1897: ALSA: hda - Set stream_pm ops automatically by generic parser] resulted in regressions on some Realtek and VIA codecs because these drivers set patch_ops after calling the generic parser, thus stream_pm got cleared to NULL again. I haven't noticed since I tested with IDT codec. Restore (partial revert) the stream_pm ops for them to fix the regression.
