Message-Id: <200711292052.lATKqpbB006837@imap1.linux-foundation.org> Date: Thu, 29 Nov 2007 12:52:51 -0800 From: akpm@...ux-foundation.org To: cmm@...ibm.com Cc: tytso@....edu, linux-ext4@...r.kernel.org, akpm@...ux-foundation.org, sandeen@...hat.com Subject: [patch 5/8] ext4: Fix oops with jbd-stats-through-procfs and external journal From: Eric Sandeen <sandeen@...hat.com> When using an external device for the journal, jbd2_stats_proc_init() wants to use journal->j_dev in its call to bdevname() but it's not assigned yet, resulting in an oops.
