Merge tag 'nfs-for-3.17-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull NFS client updates from Trond Myklebust: "Highlights include: - stable fix for a bug in nfs3_list_one_acl() - speed up NFS path walks by supporting LOOKUP_RCU - more read/write code cleanups - pNFS fixes for layout return on close - fixes for the RCU handling in the rpcsec_gss code - more NFS/RDMA fixes" * tag 'nfs-for-3.17-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: (79 commits) nfs: reject changes to resvport and sharecache during remount NFS: Avoid infinite loop when RELEASE_LOCKOWNER getting expired error SUNRPC: remove all refcounting of groupinfo from rpcauth_lookupcred NFS: fix two problems in lookup_revalidate in RCU-walk NFS: allow lockless access to access_cache NFS: teach nfs_lookup_verify_inode to handle LOOKUP_RCU NFS: teach nfs_neg_need_reval to understand LOOKUP_RCU NFS: support RCU_WALK in nfs_permission() sunrpc/auth: allow lockless (rcu) lookup of credential cache. NFS: prepare for RCU-walk support but pushing tests later in code. NFS: nfs4_lookup_revalidate: only evaluate parent if it will be used. NFS: add checks for returned value of try_module_get() nfs: clear_request_commit while holding i_lock pnfs: add pnfs_put_lseg_async pnfs: find swapped pages on pnfs commit lists too nfs: fix comment and add warn_on for PG_INODE_REF nfs: check wait_on_bit_lock err in page_group_lock sunrpc: remove "ec" argument from encrypt_v2 operation sunrpc: clean up sparse endianness warnings in gss_krb5_wrap.c sunrpc: clean up sparse endianness warnings in gss_krb5_seal.c ...
