From 91ef4caf800030fa6e5224b8a41f8c74787b303d Mon Sep 17 00:00:00 2001 From: Duane Griffin Date: Fri, 11 Jul 2008 19:27:31 -0400 Subject: ext4: handle corrupted orphan list at mount If the orphan node list includes valid, untruncatable nodes with nlink > 0 the ext4_orphan_cleanup loop which attempts to delete them will not do so, causing it to loop forever. Fix by checking for such nodes in the ext4_orphan_get function. This patch fixes the second case (image hdb.20000009.softlockup.gz) reported in http://bugzilla.kernel.org/show_bug.cgi?id=10882.
