From 1a2bf2eefb63a267aea7f3f80d6ac59160e20810 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Thu, 19 Jul 2007 00:27:43 +0200 Subject: [DLM] Fix memory leak in dlm_add_member() when dlm_node_weight() returns less than zero There's a memory leak in fs/dlm/member.c::dlm_add_member(). If "dlm_node_weight(ls->ls_name, nodeid)" returns < 0, then we'll return without freeing the memory allocated to the (at that point yet unused) 'memb'. This patch frees the allocated memory in that case and thus avoids the leak.
