Merge tag 'nfs-for-3.18-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull NFS client updates from Trond Myklebust: "Highlights include: Stable fixes: - fix an NFSv4.1 state renewal regression - fix open/lock state recovery error handling - fix lock recovery when CREATE_SESSION/SETCLIENTID_CONFIRM fails - fix statd when reconnection fails - don't wake tasks during connection abort - don't start reboot recovery if lease check fails - fix duplicate proc entries Features: - pNFS block driver fixes and clean ups from Christoph - More code cleanups from Anna - Improve mmap() writeback performance - Replace use of PF_TRANS with a more generic mechanism for avoiding deadlocks in nfs_release_page" * tag 'nfs-for-3.18-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: (66 commits) NFSv4.1: Fix an NFSv4.1 state renewal regression NFSv4: fix open/lock state recovery error handling NFSv4: Fix lock recovery when CREATE_SESSION/SETCLIENTID_CONFIRM fails NFS: Fabricate fscache server index key correctly SUNRPC: Add missing support for RPC_CLNT_CREATE_NO_RETRANS_TIMEOUT NFSv3: Fix missing includes of nfs3_fs.h NFS/SUNRPC: Remove other deadlock-avoidance mechanisms in nfs_release_page() NFS: avoid waiting at all in nfs_release_page when congested. NFS: avoid deadlocks with loop-back mounted NFS filesystems. MM: export page_wakeup functions SCHED: add some "wait..on_bit...timeout()" interfaces. NFS: don't use STABLE writes during writeback. NFSv4: use exponential retry on NFS4ERR_DELAY for async requests. rpc: Add -EPERM processing for xs_udp_send_request() rpc: return sent and err from xs_sendpages() lockd: Try to reconnect if statd has moved SUNRPC: Don't wake tasks during connection abort Fixing lease renewal nfs: fix duplicate proc entries pnfs/blocklayout: Fix a 64-bit division/remainder issue in bl_map_stripe ...
