Merge tag 'nfs-for-3.18-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull NFS client updates from Trond Myklebust:
"Highlights include:
Stable fixes:
- fix an uninitialised pointer Oops in the writeback error path
- fix a bogus warning (and early exit from the loop) in nfs_generic_pgio()
Features:
- Add NFSv4.2 SEEK feature and client support for lseek(SEEK_HOLE/SEEK_DATA)
Other fixes:
- pnfs: replace broken pnfs_put_lseg_async
- Remove dead prototype for nfs4_insert_deviceid_node"
