From 5cf1c4b19db99d21d44c2ab457cfd44eb86b4439 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Fri, 5 Dec 2008 19:02:53 -0500 Subject: NSM: Add dprintk() calls in nsm_find and nsm_release Introduce some dprintk() calls in fs/lockd/mon.c that are enabled by the NLMDBG_MONITOR flag. These report when we find, create, and release nsm_handles. Signed-off-by: Chuck Lever Signed-off-by: J.
