Subject[PATCH 09/35] ocfs2: Add ecc and checksums to ocfs2 xattr buckets.
DateThu, 25 Dec 2008 10:04:24 -0800
From: Joel Becker <joel.becker@oracle.com>

The xattr bucket can span multiple blocks on disk. We have wrappers
for this structure in the code. We use the new multi-block ecc calls to
calculate and validate the bucket.
