[PATCH v3 05/11] iotests: Improve iotest 194 to mirror data
Posted by Eric Blake 5 months, 1 week ago
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.
