From 418befec187066f6f107f1cf986d29bf77ca498c Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Wed, 8 Mar 2006 03:54:24 +0000 Subject: r14011: - added a ntvfs_notify op to allow backends to support change notify - converted the nttrans server side code to be async (needed for change notify) This is the start of some work on supporting change notify via a new approach. More soon.
