Merge tag 'nfs-for-4.8-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull NFS client updates from Trond Myklebust: "Highlights include: Stable bugfixes: - nfs: don't create zero-length requests - several LAYOUTGET bugfixes Features: - several performance related features - more aggressive caching when we can rely on close-to-open cache consistency - remove serialisation of O_DIRECT reads and writes - optimise several code paths to not flush to disk unnecessarily. However allow for the idiosyncracies of pNFS for those layout types that need to issue a LAYOUTCOMMIT before the metadata can be updated on the server. - SUNRPC updates to the client data receive path - pNFS/SCSI support RH/Fedora dm-mpath device nodes - pNFS files/flexfiles can now use unprivileged ports when the generic NFS mount options allow it. Bugfixes: - Don't use RDMA direct data placement together with data integrity or privacy security flavours - Remove the RDMA ALLPHYSICAL memory registration mode as it has potential security holes. - Several layout recall fixes to improve NFSv4.1 protocol compliance. - Fix an Oops in the pNFS files and flexfiles connection setup to the DS - Allow retry of operations that used a returned delegation stateid - Don't mark the inode as revalidated if a LAYOUTCOMMIT is outstanding - Fix writeback races in nfs4_copy_range() and nfs42_proc_deallocate()" * tag 'nfs-for-4.8-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: (104 commits) pNFS: Actively set attributes as invalid if LAYOUTCOMMIT is outstanding NFSv4: Clean up lookup of SECINFO_NO_NAME NFSv4.2: Fix warning "variable ‘stateids’ set but not used" NFSv4: Fix warning "no previous prototype for ‘nfs4_listxattr’" SUNRPC: Fix a compiler warning in fs/nfs/clnt.c pNFS: Remove redundant smp_mb() from pnfs_init_lseg() pNFS: Cleanup - do layout segment initialisation in one place pNFS: Remove redundant stateid invalidation pNFS: Remove redundant pnfs_mark_layout_returned_if_empty() pNFS: Clear the layout metadata if the server changed the layout stateid pNFS: Cleanup - don't open code pnfs_mark_layout_stateid_invalid() NFS: pnfs_mark_matching_lsegs_return() should match the layout sequence id pNFS: Do not set plh_return_seq for non-callback related layoutreturns pNFS: Ensure layoutreturn acts as a completion for layout callbacks pNFS: Fix CB_LAYOUTRECALL stateid verification pNFS: Always update the layout barrier seqid on LAYOUTGET pNFS: Always update the layout stateid if NFS_LAYOUT_INVALID_STID is set pNFS: Clear the layout return tracking on layout reinitialisation pNFS: LAYOUTRETURN should only update the stateid if the layout is valid nfs: don't create zero-length requests ...
