Merge branch 'for-3.15' of git://linux-nfs.org/~bfields/linux
Pull nfsd updates from Bruce Fields: "Highlights: - server-side nfs/rdma fixes from Jeff Layton and Tom Tucker - xdr fixes (a larger xdr rewrite has been posted but I decided it would be better to queue it up for 3.16). - miscellaneous fixes and cleanup from all over (thanks especially to Kinglong Mee)" * 'for-3.15' of git://linux-nfs.org/~bfields/linux: (36 commits) nfsd4: don't create unnecessary mask acl nfsd: revert v2 half of "nfsd: don't return high mode bits" nfsd4: fix memory leak in nfsd4_encode_fattr() nfsd: check passed socket's net matches NFSd superblock's one SUNRPC: Clear xpt_bc_xprt if xs_setup_bc_tcp failed NFSD/SUNRPC: Check rpc_xprt out of xs_setup_bc_tcp SUNRPC: New helper for creating client with rpc_xprt NFSD: Free backchannel xprt in bc_destroy NFSD: Clear wcc data between compound ops nfsd: Don't return NFS4ERR_STALE_STATEID for NFSv4.1+ nfsd4: fix nfs4err_resource in 4.1 case nfsd4: fix setclientid encode size nfsd4: remove redundant check from nfsd4_check_resp_size nfsd4: use more generous NFS4_ACL_MAX nfsd4: minor nfsd4_replay_cache_entry cleanup nfsd4: nfsd4_replay_cache_entry should be static nfsd4: update comments with obsolete function name rpc: Allow xdr_buf_subsegment to operate in-place NFSD: Using free_conn free connection SUNRPC: fix memory leak of peer addresses in XPRT ...
