From 355ed4e141203fd7266ef9d90d57be0c61bd1aa4 Mon Sep 17 00:00:00 2001 From: KaiGai Kohei Date: Sat, 24 Jun 2006 09:15:36 +0900 Subject: [JFFS2][XATTR] Fix memory leak with jffs2_xattr_ref If xattr_ref is associated with an orphan inode_cache on filesystem mounting, those xattr_refs are not released even if this inode_cache is released. This patch enables to call jffs2_xattr_delete_inode() for such a irregular inode_cachde too.
