  nfs: Fix an oops caused by using other thread's stack space in ASYNC mode (2015-07-28 09:07:03 -0400)

----------------------------------------------------------------
NFS client bugfixes for Linux 4.2

Highlights include:

Stable patches:
- Fix a situation where the client uses the wrong (zero) stateid.
- Fix a memory leak in nfs_do_recoalesce

Bugfixes:
- Plug a memory leak when ->prepare_layoutcommit fails
- Fix an Oops in the NFSv4 open code
- Fix a backchannel deadlock
- Fix a livelock in sunrpc when sendmsg fails due to low memory availability
- Don't revalidate the mapping if both size and change attr are up to date
- Ensure we don't miss a file extension when doing pNFS
- Several fixes to handle NFSv4.1 sequence operation status bits correctly
- Several pNFS layout return bugfixes

Trond Myklebust (24):
      SUNRPC: Don't reencode message if transmission failed with ENOBUFS
      SUNRPC: Don't confuse ENOBUFS with a write_space issue
      NFSv4.1: Handle SEQ4_STATUS_EXPIRED_SOME_STATE_REVOKED status bit correctly.
      NFSv4.1: Handle SEQ4_STATUS_RECALLABLE_STATE_REVOKED status bit correctly
      NFSv4.1: Handle SEQ4_STATUS_BACKCHANNEL_FAULT correctly
      NFSv4.1: nfs41_sequence_done should handle sequence flag errors
      NFSv4: Leases are renewed in sequence_done when we have sessions
      NFSv4.2/flexfiles: Fix a typo in the flexfiles layoutstats code
      pNFS: Layoutreturn must invalidate all existing layout segments.
      pNFS: pnfs_roc_drain should return 'true' when sleeping
      pNFS: Fix races between return-on-close and layoutreturn.
      pNFS: pnfs_roc_drain() fix a race with open
      pNFS: Don't throw out valid layout segments
      SUNRPC: Fix a backchannel deadlock
      SUNRPC: xprt_complete_bc_request must also decrement the free slot count
      NFSv4: We must set NFS_OPEN_STATE flag in nfs_resync_open_stateid_locked
      NFSv4/pnfs: Ensure we don't miss a file extension
      NFS: Don't revalidate the mapping if both size and change attr are up to date
      NFS: Set NFS_INO_REVAL_PAGECACHE if the change attribute is uninitialised
      NFS: Remove the "NFS_CAP_CHANGE_ATTR" capability
      NFS: nfs_mark_for_revalidate should always set NFS_INO_REVAL_PAGECACHE
      NFS: Fix a memory leak in nfs_do_recoalesce
