Subject: [PATCH V3 03/12] xfs: Rename MAXEXTNUM, MAXAEXTNUM to XFS_IFORK_EXTCNT_MAXS32, XFS_IFORK_EXTCNT_MAXS16
Date: Thu, 16 Sep 2021 15:36:38 +0530	[thread overview]
Message-ID: <20210916100647.176018-4-chandan.babu@oracle.com> (raw)
In-Reply-To: <20210916100647.176018-1-chandan.babu@oracle.com>

In preparation for introducing larger extent count limits, this commit renames
existing extent count limits based on their signedness and width.
