Subject: [PATCH 03/18] xfs: define sparse inode chunks v5 sb feature bit and helper function
Date: Thu, 24 Jul 2014 10:22:53 -0400	[thread overview]
Message-ID: <1406211788-63206-4-git-send-email-bfoster@redhat.com> (raw)
In-Reply-To: <1406211788-63206-1-git-send-email-bfoster@redhat.com>

The sparse inode chunks feature will use the helper function to enable
the allocation of sparse inode chunks. The incompatible feature bit is
set on disk once a sparse inode chunk is allocated to prevent older
drivers from mounting an fs with sparse chunks.

Note that the feature is hardcoded disabled and the feature bit not
included in the all features mask until fully implemented.
