From b62205986a73a40e4fc174d2ef668e3895e925bc Mon Sep 17 00:00:00 2001 From: "Artem B. Bityuckiy" Date: Tue, 12 Jul 2005 17:37:12 +0100 Subject: [PATCH] [JFFS2] Init locks early during mount In case of a mount error locks might be uninitialized but accessed by the resulting call to jffs2_kill_sb().
