Subject: [PULL 05/14] iotests: Improve iotest 194 to mirror data
Date: Wed, 14 May 2025 21:28:48 -0500	[thread overview]
Message-ID: <20250515022904.575509-21-eblake@redhat.com> (raw)
In-Reply-To: <20250515022904.575509-16-eblake@redhat.com>

Mirroring a completely sparse image to a sparse destination should be
practically instantaneous.  It isn't yet, but the test will be more
realistic if it has some non-zero to mirror as well as the holes.
