From: "Theodore Ts'o" <tytso@....edu>
To: linux-ext4@...r.kernel.org
Subject: JBD2 naming cleanups patch
The jbd_to_jbd2_naming_cleanups.patch blew up if compiled with
CONFIG_JBD2_DEBUG, because JBD2_POISON_FREE wasn't defined in poison.h.
So I fixed up this patch as follows.
- Ted
jbd2: JBD_XXX to JBD2_XXX naming cleanup
From: Mingming Cao <cmm@...ibm.com>
change JBD_XXX macros to JBD2_XXX in JBD2/Ext4
