From aef2c5d69956c72f8b0bd2285283e8879ed8603d Mon Sep 17 00:00:00 2001

Date: Wed, 24 Dec 1997 09:30:56 +0000
Subject: Added SIGUSR1/SIGUSR2 handling. Sending nmbd/smbd a SIGUSR1 will
 raise the debug level by one (capped at 10) sending a SIGUSR2 will lower it
 (lower limit at zero). Jeremy. (This used to be commit
 6a3cb6f4b46129e4d799a24d34cdb9460ed8910f)
