Subject: [PATCH 3/3] ext4: mark metadata blocks using bh flags
Date: Sat, 20 Apr 2013 20:07:08 -0400	[thread overview]
Message-ID: <1366502828-7793-3-git-send-email-tytso@mit.edu> (raw)
In-Reply-To: <1366502828-7793-1-git-send-email-tytso@mit.edu>

This allows metadata writebacks which are issued via block device
writeback to be sent with the current write request flags.
