Subject: [PATCH 00/26] pNFS updates for v4.10
Date: Thu, 1 Dec 2016 17:18:56 -0500 [thread overview]
Message-ID: <20161201221922.15657-1-trond.myklebust@primarydata.com> (raw)
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.
Trond Myklebust (26):
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
stateid
pNFS: Force a retry of LAYOUTGET if the stateid doesn't match our
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: Get rid of unnecessary layout parameter in encode_layoutreturn
callback
pNFS: Don't mark layout segments invalid on layoutreturn in pnfs_roc
NFSv4: Fix missing operation accounting in NFS4_dec_delegreturn_sz
NFSv4: Add encode/decode of the layoutreturn op in CLOSE
NFSv4: Add encode/decode of the layoutreturn op in DELEGRETURN
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
pNFS: Fix bugs in _pnfs_return_layout
pNFS: Sync the layout state bits in pnfs_cache_lseg_for_layoutreturn
pNFS: Don't mark the layout as freed if the last lseg is marked for
return
pNFS: Wait on outstanding layoutreturns to complete in pnfs_roc()
pNFS: Skip invalid stateids when doing a bulk destroy
