Subject: [PATCH 18/18] xfs: enable sparse inode chunks for v5 superblocks
Date: Thu, 24 Jul 2014 10:23:08 -0400	[thread overview]
Message-ID: <1406211788-63206-19-git-send-email-bfoster@redhat.com> (raw)
In-Reply-To: <1406211788-63206-1-git-send-email-bfoster@redhat.com>

Enable the use and processing of sparse inode chunks.  Fix the
xfs_sb_version_hassparseinodes() helper to allow the allocation of
sparse chunks on v5 format superblocks. Add the incompat. feature bit to
the *_ALL mask such that fs' with sparse chunks can be mounted.
