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" * tag 'nfs-for-5.9-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: (32 commits) NFS: Fix flexfiles read failover fs: nfs: delete repeated words in comments rpc_pipefs: convert comma to semicolon nfs: Fix getxattr kernel panic and memory overflow NFS: Don't return layout segments that are in use NFS: Don't move layouts to plh_return_segs list while in use NFS: Add layout segment info to pnfs read/write/commit tracepoints NFS: Add tracepoints for layouterror and layoutstats. NFS: Report the stateid + status in trace_nfs4_layoutreturn_on_close() SUNRPC dont update timeout value on connection reset nfs: nfs_file_write() should check for writeback errors nfs: ensure correct writeback errors are returned on close() NFSv4.2: xattr cache: get rid of cache discard work queue NFS: remove redundant initialization of variable result NFSv4.0 allow nconnect for v4.0 freezer: Add unsafe versions of freezable_schedule_timeout_interruptible for NFS sunrpc: destroy rpc_inode_cachep after unregister_filesystem NFSv4.2: add client side xattr caching. NFSv4.2: hook in the user extended attribute handlers NFSv4.2: add the extended attribute proc functions. ...
