       - 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"
