Hi Linus,

The following changes since commit 74bf8efb5fa6e958d2d7c7917b8bb672085ec0c6:

Linux 4.4-rc7 (2015-12-27 18:17:37 -0800)

are available in the git repository at:

git://git.linux-nfs.org/projects/trondmy/linux-nfs.git tags/nfs-for-4.5-1

for you to fetch changes up to 44aab3e09ef947e546ee61c5082c41b86dd15e53:

NFS: Fix a compile warning about unused variable in
nfs_generic_pg_pgios() (2016-01-08 08:12:47 -0500)

Please note that Stephen saw a conflict between commits:
926ea40a7ee2 ("NFSv4: Fix a compile warning about no prototype for
nfs4_ioctl()")
and
04b38d601239 ("vfs: pull btrfs clone API to vfs layer")
from Al's vfs tree. The fixup should be trivial.

Cheers
Trond

----------------------------------------------------------------
NFS client updates for Linux 4.5

Highlights include:

Stable fixes:
- Fix a regression in the SunRPC socket polling code
- Fix the attribute cache revalidation code
- Fix race in __update_open_stateid()
- Fix an lo->plh_block_lgets imbalance in layoutreturn
- Fix an Oopsable typo in ff_mirror_match_fh()

Features:
- pNFS layout recall performance improvements.
- pNFS/flexfiles: Support server-supplied layoutstats sampling period

Bugfixes + cleanups:
- NFSv4: Don't perform cached access checks before we've OPENed the file
- Fix starvation issues with background flushes
- Reclaim writes should be flushed as unstable writes if there are already
entries in the commit lists
- Various bugfixes from Chuck to fix NFS/RDMA send queue ordering problems
- Ensure that we propagate fatal layoutget errors back to the application
- Fixes for sundry flexfiles layoutstats bugs
- Fix files/flexfiles to not cache invalidated layouts in the DS commit buckets
