Merge tag 'nfs-for-4.19-1' of git://git.linux-nfs.org/projects/anna/linux-nfs
Pull NFS client updates from Anna Schumaker: "These patches include adding async support for the v4.2 COPY operation. I think Bruce is planning to send the server patches for the next release, but I figured we could get the client side out of the way now since it's been in my tree for a while. This shouldn't cause any problems, since the server will still respond with synchronous copies even if the client requests async. Features: - Add support for asynchronous server-side COPY operations Stable bufixes: - Fix an off-by-one in bl_map_stripe() (v3.17+) - NFSv4 client live hangs after live data migration recovery (v4.9+) - xprtrdma: Fix disconnect regression (v4.18+) - Fix locking in pnfs_generic_recover_commit_reqs (v4.14+) - Fix a sleep in atomic context in nfs4_callback_sequence() (v4.9+) Other bugfixes and cleanups: - Optimizations and fixes involving NFS v4.1 / pNFS layout handling - Optimize lseek(fd, SEEK_CUR, 0) on directories to avoid locking - Immediately reschedule writeback when the server replies with an error - Fix excessive attribute revalidation in nfs_execute_ok() - Add error checking to nfs_idmap_prepare_message() - Use new vm_fault_t return type - Return a delegation when reclaiming one that the server has recalled - Referrals should inherit proto setting from parents - Make rpc_auth_create_args a const - Improvements to rpc_iostats tracking - Fix a potential reference leak when there is an error processing a callback - Fix rmdir / mkdir / rename nlink accounting - Fix updating inode change attribute - Fix error handling in nfsn4_sp4_select_mode() - Use an appropriate work queue for direct-write completion - Don't busy wait if NFSv4 session draining is interrupted" * tag 'nfs-for-4.19-1' of git://git.linux-nfs.org/projects/anna/linux-nfs: (54 commits) pNFS: Remove unwanted optimisation of layoutget pNFS/flexfiles: ff_layout_pg_init_read should exit on error pNFS: Treat RECALLCONFLICT like DELAY... pNFS: When updating the stateid in layoutreturn, also update the recall range NFSv4: Fix a sleep in atomic context in nfs4_callback_sequence() NFSv4: Fix locking in pnfs_generic_recover_commit_reqs NFSv4: Fix a typo in nfs4_init_channel_attrs() NFSv4: Don't busy wait if NFSv4 session draining is interrupted NFS recover from destination server reboot for copies NFS add a simple sync nfs4_proc_commit after async COPY NFS handle COPY ERR_OFFLOAD_NO_REQS NFS send OFFLOAD_CANCEL when COPY killed NFS export nfs4_async_handle_error NFS handle COPY reply CB_OFFLOAD call race NFS add support for asynchronous COPY NFS COPY xdr handle async reply NFS OFFLOAD_CANCEL xdr NFS CB_OFFLOAD xdr NFS: Use an appropriate work queue for direct-write completion NFSv4: Fix error handling in nfs4_sp4_select_mode() ...
