Merge tag 'nfs-for-5.9-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs

Pull NFS client updates from Trond Myklebust:
"Stable fixes:
- pNFS: Don't return layout segments that are being used for I/O
- pNFS: Don't move layout segments off the active list when being used for I/O

Features:
- NFS: Add support for user xattrs through the NFSv4.2 protocol
- NFS: Allow applications to speed up readdir+statx() using AT_STATX_DONT_SYNC
- NFSv4.0 allow nconnect for v4.0

Bugfixes and cleanups:
- nfs: ensure correct writeback errors are returned on close()
- nfs: nfs_file_write() should check for writeback errors
- nfs: Fix getxattr kernel panic and memory overflow
- NFS: Fix the pNFS/flexfiles mirrored read failover code
- SUNRPC: dont update timeout value on connection reset
- freezer: Add unsafe versions of freezable_schedule_timeout_interruptible for NFS
- sunrpc: destroy rpc_inode_cachep after unregister_filesystem"

NFSv4.2: xattr cache: get rid of cache discard work queue

Caches should be small enough to discard them inline, so do that
instead of using a work queue.

NFSv4.2: add client side xattr caching.

Implement client side caching for NFSv4.2 extended attributes. The cache
is a per-inode hashtable, with name/value entries. There is one special
entry for the listxattr cache.

NFS inodes have a pointer to a cache structure. The cache structure is
allocated on demand, freed when the cache is invalidated.

Memory shrinkers keep the size in check. Large entries (> PAGE_SIZE)
are collected by a separate shrinker, and freed more aggressively
than others.
