Subject: [PATCH] xfs: update max log size
Date: Mon, 11 May 2009 12:06:17 -0400 [thread overview]
Message-ID: <20090511160609.GA18278@infradead.org> (raw)
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.
