From a345da3e8f28ff69e1b14df78f7ddc6e7b78b726 Mon Sep 17 00:00:00 2001 From: David Teigland Date: Fri, 18 Aug 2006 11:54:25 -0500 Subject: [PATCH] [DLM] dump rsb and locks on assert Introduce new function dlm_dump_rsb() to call within assertions instead of dlm_print_rsb(). The new function dumps info about all locks on the rsb in addition to rsb details.
