Subject: [PATCH v4 04/18] xfs: add sparse inode chunk alignment superblock field
Date: Thu, 12 Feb 2015 13:17:11 -0500	[thread overview]
Message-ID: <1423765045-15791-5-git-send-email-bfoster@redhat.com> (raw)
In-Reply-To: <1423765045-15791-1-git-send-email-bfoster@redhat.com>

Add sb_spino_align to the superblock to specify sparse inode chunk
alignment. This also currently represents the minimum allowable sparse
chunk allocation size.
