From 57638bf3aa64facd9eba0e018b5773f5d2da6c2b Mon Sep 17 00:00:00 2001 From: David Teigland Date: Mon, 23 Apr 2012 14:08:52 -0500 Subject: [PATCH] dlm: avoid unnecessary search in search_rsb If the rsb is found in the "keep" tree, but is not the right type (i.e. not MASTER), we can return immediately with the result. There's no point in going on to search the "toss" list as if we hadn't found it.
