From a8dfdaeb7a8b1295f45d9d208dd27e6e20113d1b Mon Sep 17 00:00:00 2001 From: Andy Adamson Date: Fri, 28 Aug 2009 08:45:02 -0400 Subject: nfsd41: use session maxreqs for sequence target and highest slotid This fixes a bug in the sequence operation reply. The sequence operation returns the highest slotid it will accept in the future in sr_highest_slotid, and the highest slotid it prefers the client to use. Since we do not re-negotiate the session slot table yet, these should both always be set to the session ca_maxrequests. Signed-off-by: Andy Adamson Signed-off-by: J.
