From b0679c63db655fa12007558e267bc0eb1d486fdb Mon Sep 17 00:00:00 2001 From: Jason Wessel Date: Wed, 21 Jul 2010 19:27:07 -0500 Subject: [PATCH] debug_core,kdb: fix kgdb_connected bit set in the wrong place Immediately following an exit from the kdb shell the kgdb_connected variable should be set to zero, unless there are breakpoints planted. If the kgdb_connected variable is not zeroed out with kdb, it is impossible to turn off kdb. This patch is merely a work around for now, the real fix will check for the breakpoints.
