Merge branch 'for-3.19' of git://linux-nfs.org/~bfields/linux
Pull nfsd updates from Bruce Fields: "A comparatively quieter cycle for nfsd this time, but still with two larger changes: - RPC server scalability improvements from Jeff Layton (using RCU instead of a spinlock to find idle threads). - server-side NFSv4.2 ALLOCATE/DEALLOCATE support from Anna Schumaker, enabling fallocate on new clients" * 'for-3.19' of git://linux-nfs.org/~bfields/linux: (32 commits) nfsd4: fix xdr4 count of server in fs_location4 nfsd4: fix xdr4 inclusion of escaped char sunrpc/cache: convert to use string_escape_str() sunrpc: only call test_bit once in svc_xprt_received fs: nfsd: Fix signedness bug in compare_blob sunrpc: add some tracepoints around enqueue and dequeue of svc_xprt sunrpc: convert to lockless lookup of queued server threads sunrpc: fix potential races in pool_stats collection sunrpc: add a rcu_head to svc_rqst and use kfree_rcu to free it sunrpc: require svc_create callers to pass in meaningful shutdown routine sunrpc: have svc_wake_up only deal with pool 0 sunrpc: convert sp_task_pending flag to use atomic bitops sunrpc: move rq_cachetype field to better optimize space sunrpc: move rq_splice_ok flag into rq_flags sunrpc: move rq_dropme flag into rq_flags sunrpc: move rq_usedeferral flag to rq_flags sunrpc: move rq_local field to rq_flags sunrpc: add a generic rq_flags field to svc_rqst and move rq_secure to it nfsd: minor off by one checks in __write_versions() sunrpc: release svc_pool_map reference when serv allocation fails ...
