[Qemu-devel] [PATCH 1/2] mirror: Release the dirty bitmap if mirror_start_job() fails

[Alberto Garcia]

At the moment I don't see how to make this function fail after the
dirty bitmap has been created, but if that was possible then we would
hit the assert(QLIST_EMPTY(&bs->dirty_bitmaps)) in bdrv_close().
