Merge tag 'nfs-for-3.14-4' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull NFS client bugfixes from Trond Myklebust: "Highlights include stable fixes for the following bugs: - General performance regression due to NFS_INO_INVALID_LABEL being set when the server doesn't support labeled NFS - Hang in the RPC code due to a socket out-of-buffer race - Infinite loop when trying to establish the NFSv4 lease - Use-after-free bug in the RPCSEC gss code. - nfs4_select_rw_stateid is returning with a non-zero error value on success Other bug fixes: - Potential memory scribble in the RPC bi-directional RPC code - Pipe version reference leak - Use the correct net namespace in the new NFSv4 migration code" * tag 'nfs-for-3.14-4' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: NFS fix error return in nfs4_select_rw_stateid NFSv4: Use the correct net namespace in nfs4_update_server SUNRPC: Fix a pipe_version reference leak SUNRPC: Ensure that gss_auth isn't freed before its upcall messages SUNRPC: Fix potential memory scribble in xprt_free_bc_request() SUNRPC: Fix races in xs_nospace() SUNRPC: Don't create a gss auth cache unless rpc.gssd is running NFS: Do not set NFS_INO_INVALID_LABEL unless server supports labeled NFS
