Subject: [PATCH v3 2/9] nfs: check for POSIX lock capability on server even for flock locks
Date: Fri, 16 Sep 2016 16:27:04 -0400	[thread overview]
Message-ID: <1474057631-31209-3-git-send-email-jlayton@redhat.com> (raw)
In-Reply-To: <1474057631-31209-1-git-send-email-jlayton@redhat.com>

We may end up in here with a FL_FLOCK lock request. We translate those
to whole-file NFSv4 locks and send them on to the server, so we need to
verify that the server supports them no matter what sort of lock request
this is.
