Subject: [PATCH 4/9] xfs: test xfs_copy doesn't do cached read before libxfs_mount
Date: Tue, 28 Jun 2022 13:21:40 -0700	[thread overview]
Message-ID: <165644770013.1045534.5572366430392518217.stgit@magnolia> (raw)
In-Reply-To: <165644767753.1045534.18231838177395571946.stgit@magnolia>

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

This is a regression test for an xfs_copy fix that ensures that it
doesn't perform a cached read of an XFS filesystem prior to initializing
libxfs, since the xfs_mount (and hence the buffer cache) isn't set up
yet.
