And actually I didn't read Casey's report carefully: he was just complaining about delegation stateid's. I don't think they matter much, as their seqid field never changes, but may as well use the same as the others. And while we're there, make this uniform for v4.0 as well. --b. commit 80809fa40f8cfb3cf0bf006e3218bbd00584b38d Author: J. Bruce Fields <bfields@redhat.com> Date: Wed Aug 31 15:47:21 2011 -0400 nfsd4: make delegation stateid's seqid start at 1 Thanks to Casey for reminding me that 5661 gives a special meaning to a value of 0 in the stateid's seqid field, so all stateid's should start out with si_generation 1. We were doing that in the open and lock cases for minorversion 1, but not for the delegation stateid, and not for openstateid's with v4.0. It doesn't *really* matter much for v4.0 or for delegation stateid's (which never get the seqid field incremented), but we may as well do the same for all of them.
