Subject: [PATCH] fs: ext4: Printing debug is now configurable
Date: Tue, 30 Apr 2013 14:51:00 -0700	[thread overview]
Message-ID: <1367358660-940-1-git-send-email-taysom@chromium.org> (raw)

Printing the "truncating inode" and "deleting unreferenced inode"
messages is now controlled by the "debug" option to mount.
These messages were filling the /var/log/messages file and
are normal for ext4 file system recovery.

Tested by opening several files, unlinking them, then
crashing the system, rebooting the system and examining
/var/log/messages.

Addresses the problem described in http://crbug.com/220976
