Subject: [PATCH 6/9] ext4: set bg_itable_unused when resizing
Date: Thu, 13 Sep 2012 18:49:13 -0400 [thread overview]
Message-ID: <1347576556-5725-7-git-send-email-tytso@mit.edu> (raw)
In-Reply-To: <1347576556-5725-1-git-send-email-tytso@mit.edu>
Set bg_itable_unused for file systems that have uninit_bg enabled.
This will speed up the first e2fsck run after the file system is
resized.
