Subject: [PATCH v2 01/17] xfs: add sparse inode chunk alignment superblock field
Date: Mon, 3 Nov 2014 11:12:10 -0500 [thread overview]
Message-ID: <1415031146-9107-2-git-send-email-bfoster@redhat.com> (raw)
In-Reply-To: <1415031146-9107-1-git-send-email-bfoster@redhat.com>
Add sb_spinoalignmt to the superblock to specify sparse inode chunk
alignment. This also currently represents the minimum allowable sparse
chunk allocation size.
