[PATCH] nfsd4: relax new lock seqid check
We're insisting that the lock sequence id field passed in the open_to_lockowner struct always be zero. This is probably thanks to the sentence in rfc3530: "The first request issued for any given lock_owner is issued with a sequence number of zero." But there doesn't seem to be any problem with allowing initial sequence numbers other than zero. And currently this is causing lock reclaims from the Linux client to fail. In the spirit of "be liberal in what you accept, conservative in what you send", we'll relax the check (and patch the Linux client as well). Signed-off-by: J.
