Subject: [PATCH V3 07/12] xfs: Rename inode's extent counter fields based on their width
Date: Thu, 16 Sep 2021 15:36:42 +0530	[thread overview]
Message-ID: <20210916100647.176018-8-chandan.babu@oracle.com> (raw)
In-Reply-To: <20210916100647.176018-1-chandan.babu@oracle.com>

This commit renames extent counter fields in "struct xfs_dinode" and "struct
xfs_log_dinode" based on the width of the fields. As of this commit, the
32-bit field will be used to count data fork extents and the 16-bit field will
be used to count attr fork extents.

This change is done to enable a future commit to introduce a new 64-bit extent
counter field.
