Merge branch 'bugfixes' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
* 'bugfixes' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: NFS: Fix a regression in nfs_file_llseek() NFSv4: Do not accept delegated opens when a delegation recall is in effect NFSv4: Ensure correct locking when accessing the 'lock_states' list NFSv4.1: Ensure that we handle _all_ SEQUENCE status bits. NFSv4: Don't error if we handled it in nfs4_recovery_handle_error SUNRPC: Ensure we always bump the backlog queue in xprt_free_slot SUNRPC: Fix the execution time statistics in the face of RPC restarts
