Highlights include:
- Stable patch to fix a deadlock between resends and LAYOUTRETURN
- Stable patch to not clear the layout stateid if LAYOUTRETURN is outstanding
- Stable patch to clear NFS_LAYOUT_RETURN_REQUESTED when invalidating the layout
- Stable patch to not send LAYOUTGET until the layout error has been reported
- Patches to embed LAYOUTRETURN operations in the COMPOUNDs for CLOSE and
DELEGRETURN. This fixes a set of races for the case where the server
implements return-on-close, and where the client and server disagree
on whether or not the layout was returned due to parallel OPEN and CLOSE
calls.

pNFS: Fix a deadlock between read resends and layoutreturn
pNFS: Don't clear the layout stateid if a layout return is outstanding
pNFS: Clear NFS_LAYOUT_RETURN_REQUESTED when invalidating the layout

cache
pNFS: On error, do not send LAYOUTGET until the LAYOUTRETURN has
completed
pNFS: Fix race in pnfs_wait_on_layoutreturn
pNFS: consolidate the different range intersection tests
pNFS: Delay getting the layout header in CB_LAYOUTRECALL handlers
pNFS: Do not free layout segments that are marked for return
NFSv4: Ignore LAYOUTRETURN result if the layout doesn't match or is
invalid
pNFS: Remove spurious wake up in pnfs_layout_remove_lseg()
pNFS: Skip checking for return-on-close if the layout is invalid

pNFS: Clean up - add a helper to initialise struct layoutreturn_args
pNFS: Enable layoutreturn operation for return-on-close
pNFS: Prevent unnecessary layoutreturns after delegreturn
pNFS: Clear all layout segment state in
pnfs_mark_layout_stateid_invalid
