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() -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJXnSq8AAoJEGcL54qWCgDyn8cP/RCHLekUCq7Klh+NAnEsvuBi C7w9YpVHaC83/8Q0tR6LyFShSBJBWi/clWwO0IEomkNK/MuO77v4iyPujtEyqowK 0+eWFh/e8CsTf7mNGoi0avrHAZDB3deSuOQeYbwnNWHmd7qKVkB6tHus8LQjk852 eqwYmZ4kVr+eaCO6MttCCxJHf6datPnsbe0stiC9MpxmCzsdpZmFptfauidsFX+p 0U1IHi/ABN6zIFoc4R0iXXbaDb8ErxGw32SWIb8cnnWwdlSD8I0+Jqxs4opp23LY lAm9E0vtDJ49bJBllYl0dUmizdhJ3+NefK4aqPh5H5h3Csub+MLIsuQv/+r2AOhH qLBi5kThpspPhGHZ40VDmfV825+csUPTc8WkDaNLvb4f4UGIPakK/KBrBtxiqn+P 0etvYiWBuoBaqRVQpstawnyDdnBK0IMF/3LAULo+ozo7iTkpaZmOALYgPcBUYw2f d6pxZGeNN0GwWfjDmoUDGC07OpO/CSN5WouArgKsp5+VhjzPxjyaZLCnUhzHzXiM RV1oBytEs/iw2BLXX809noM9mqHYkdgSVmrZ9OvvDMslcLHaslpq6eaJKZSWqV2J fAws6rbcZdTFSnbAWr0OSxct6w6BijEjc3/uk+wWRtw9nkOhFqtlxI3y7k4odpW9 wVcEmRNkxfA0LlYNXWuL =WNyE -----END PGP SIGNATURE----- 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.
