- Log -----------------------------------------------------------------
commit 2deeb99fff1a90c79ba1927e1a069362e250a63c
Author: Simo Sorce <idra at samba.org>
Date: Wed Oct 15 14:03:20 2008 -0400
Transform the sequence_number operation into a normal extended operation as it should always have been. Make it also async so that it is not a special case.
