Subject: [PATCH v2.6.32.y 09/53] ext4: Fix accounting of reserved metadata blocks
Date: Sun, 30 May 2010 22:49:22 -0400 [thread overview]
Message-ID: <1275274206-3900-9-git-send-email-tytso@mit.edu> (raw)
In-Reply-To: <1275274206-3900-1-git-send-email-tytso@mit.edu>
commit ee5f4d9cdf32fd99172d11665c592a288c2b1ff4 upstream (as of v2.6.33-rc3)
Commit 0637c6f had a typo which caused the reserved metadata blocks to
not be released correctly. Fix this.
