Subject: [PATCH 3/9] xfs: hide xfs_icache_free_cowblocks
Date: Sat, 23 Jan 2021 10:53:38 -0800	[thread overview]
Message-ID: <161142801869.2173480.15740054426783383934.stgit@magnolia> (raw)
In-Reply-To: <161142800187.2173480.17415824680111946713.stgit@magnolia>

From: Darrick J. Wong <djwong@kernel.org>

Change the one remaining caller of xfs_icache_free_cowblocks to use our
new combined blockgc scan function instead, since we will soon be
combining the two scans.  This introduces a slight behavior change,
since a readonly remount now clears out post-EOF preallocations and not
just CoW staging extents.
