From c19204b0ae3f8a125118fd5d425d3c7a5f8fda9b Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Tue, 29 Apr 2008 22:00:28 -0400 Subject: ext4: don't use ext4_error in ext4_check_descriptors Because ext4_check_descriptors is called at mount time you can't use ext4_error as it calls ext4_commit_sb, which since the sb isn't all the way initialized causes bad things to happen (ie a panic). This patch changes the ext4_error's to printk's to keep this problem from happening.
