Subject: [PATCH 07/11] nfsd4: callback program number is per-session
Date: Thu, 21 Oct 2010 12:20:14 -0400	[thread overview]
Message-ID: <1287678018-9266-8-git-send-email-bfields@redhat.com> (raw)
In-Reply-To: <1287678018-9266-1-git-send-email-bfields@redhat.com>

The callback program is allowed to depend on the session which the
callback is going over.

No change in behavior yet, while we still only do callbacks over a
single session for the lifetime of the client.
