Subject: [PATCH 09/26] vfs: rename clone_verify_area to remap_verify_area
Date: Mon, 15 Oct 2018 20:10:58 -0700
Message-ID: <153965945819.1256.12048748621963848640.stgit@magnolia> (raw)
In-Reply-To: <153965939489.1256.7400115244528045860.stgit@magnolia>

From: Darrick J. Wong <darrick.wong@oracle.com>

Since we use clone_verify_area for both clone and dedupe range checks,
rename the function to make it clear that it's for both.
