[PATCH] xfs: update max log size

To: xfs@xxxxxxxxxxx
Subject: [PATCH] xfs: update max log size
From: Christoph Hellwig <hch@xxxxxxxxxxxxx>
Date: Mon, 11 May 2009 12:06:17 -0400
User-agent: Mutt/1.5.18 (2008-05-17)
Commit a6634fba3dec4a92f0a2c4e30c80b634c0576ad5 in xfsprogs increased the
maximum log size supported by mkfs.  Merged back the changes to xfs_fs.h
so the growfs enforced the same limit and the headers are in sync.
