Subject: [PATCH] iotests: add test for bitmap mirror
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

heavily based on/practically forked off iotest 257 for bitmap backups,
but:

- no writes to filter node 'mirror-top' between completion and
finalization, as those seem to deadlock?
- no inclusion of not-yet-available full/top sync modes in combination
with bitmaps
- extra set of reference/test mirrors to verify that writes in parallel
with active mirror work

intentionally keeping copyright and ownership of original test case to
honor provenance.
