Merge tag 'nfs-for-6.1-1' of git://git.linux-nfs.org/projects/anna/linux-nfs
Pull NFS client updates from Anna Schumaker: "New Features: - Add NFSv4.2 xattr tracepoints - Replace xprtiod WQ in rpcrdma - Flexfiles cancels I/O on layout recall or revoke Bugfixes and Cleanups: - Directly use ida_alloc() / ida_free() - Don't open-code max_t() - Prefer using strscpy over strlcpy - Remove unused forward declarations - Always return layout states on flexfiles layout return - Have LISTXATTR treat NFS4ERR_NOXATTR as an empty reply instead of error - Allow more xprtrdma memory allocations to fail without triggering a reclaim - Various other xprtrdma clean ups - Fix rpc_killall_tasks() races" * tag 'nfs-for-6.1-1' of git://git.linux-nfs.org/projects/anna/linux-nfs: (27 commits) NFSv4/flexfiles: Cancel I/O if the layout is recalled or revoked SUNRPC: Add API to force the client to disconnect SUNRPC: Add a helper to allow pNFS drivers to selectively cancel RPC calls SUNRPC: Fix races with rpc_killall_tasks() xprtrdma: Fix uninitialized variable xprtrdma: Prevent memory allocations from driving a reclaim xprtrdma: Memory allocation should be allowed to fail during connect xprtrdma: MR-related memory allocation should be allowed to fail xprtrdma: Clean up synopsis of rpcrdma_regbuf_alloc() xprtrdma: Clean up synopsis of rpcrdma_req_create() svcrdma: Clean up RPCRDMA_DEF_GFP SUNRPC: Replace the use of the xprtiod WQ in rpcrdma NFSv4.2: Add a tracepoint for listxattr NFSv4.2: Add tracepoints for getxattr, setxattr, and removexattr NFSv4.2: Move TRACE_DEFINE_ENUM(NFS4_CONTENT_*) under CONFIG_NFS_V4_2 NFSv4.2: Add special handling for LISTXATTR receiving NFS4ERR_NOXATTR nfs: remove nfs_wait_atomic_killable() and nfs_write_prepare() declaration NFSv4: remove nfs4_renewd_prepare_shutdown() declaration fs/nfs/pnfs_nfs.c: fix spelling typo and syntax error in comment NFSv4/pNFS: Always return layout stats on layout return for flexfiles ...
