Merge tag 'nfs-for-4.11-1' of git://git.linux-nfs.org/projects/anna/linux-nfs
Pull NFS client updates from Anna Schumaker: "Highlights include: Stable bugfixes: - NFSv4: Fix memory and state leak in _nfs4_open_and_get_state - xprtrdma: Fix Read chunk padding - xprtrdma: Per-connection pad optimization - xprtrdma: Disable pad optimization by default - xprtrdma: Reduce required number of send SGEs - nlm: Ensure callback code also checks that the files match - pNFS/flexfiles: If the layout is invalid, it must be updated before retrying - NFSv4: Fix reboot recovery in copy offload - Revert "NFSv4.1: Handle NFS4ERR_BADSESSION/NFS4ERR_DEADSESSION replies to OP_SEQUENCE" - NFSv4: fix getacl head length estimation - NFSv4: fix getacl ERANGE for sum ACL buffer sizes Features: - Add and use dprintk_cont macros - Various cleanups to NFS v4.x to reduce code duplication and complexity - Remove unused cr_magic related code - Improvements to sunrpc "read from buffer" code - Clean up sunrpc timeout code and allow changing TCP timeout parameters - Remove duplicate mw_list management code in xprtrdma - Add generic functions for encoding and decoding xdr streams Bugfixes: - Clean up nfs_show_mountd_netid - Make layoutreturn_ops static and use NULL instead of 0 to fix sparse warnings - Properly handle -ERESTARTSYS in nfs_rename() - Check if register_shrinker() failed during rpcauth_init() - Properly clean up procfs/pipefs entries - Various NFS over RDMA related fixes - Silence unititialized variable warning in sunrpc" * tag 'nfs-for-4.11-1' of git://git.linux-nfs.org/projects/anna/linux-nfs: (64 commits) NFSv4: fix getacl ERANGE for some ACL buffer sizes NFSv4: fix getacl head length estimation Revert "NFSv4.1: Handle NFS4ERR_BADSESSION/NFS4ERR_DEADSESSION replies to OP_SEQUENCE" NFSv4: Fix reboot recovery in copy offload pNFS/flexfiles: If the layout is invalid, it must be updated before retrying NFSv4: Clean up owner/group attribute decode SUNRPC: Add a helper function xdr_stream_decode_string_dup() NFSv4: Remove bogus "struct nfs_client" argument from decode_ace() NFSv4: Fix the underestimation of delegation XDR space reservation NFSv4: Replace callback string decode function with a generic NFSv4: Replace the open coded decode_opaque_inline() with the new generic NFSv4: Replace ad-hoc xdr encode/decode helpers with xdr_stream_* generics SUNRPC: Add generic helpers for xdr_stream encode/decode sunrpc: silence uninitialized variable warning nlm: Ensure callback code also checks that the files match sunrpc: Allow xprt->ops->timer method to sleep xprtrdma: Refactor management of mw_list field xprtrdma: Handle stale connection rejection xprtrdma: Properly recover FRWRs with in-flight FASTREG WRs xprtrdma: Shrink send SGEs array ...
