Subject: [PATCH 16/25] nfsd4: pass around typemask instead of flags
Date: Wed, 14 Sep 2011 07:45:12 -0400	[thread overview]
Message-ID: <1316000721-3289-17-git-send-email-bfields@redhat.com> (raw)
In-Reply-To: <1316000721-3289-1-git-send-email-bfields@redhat.com>

We're only using those flags to choose lock or open stateid's at this
point.

Signed-off-by: J. Bruce Fields <bfields@redhat.com>
