Sorry, but that is just amazingly stupid. If you really want to swap
to compressed files introduce that support in the swap code instead of
coming up with dumb driver stacks from hell.
Hi Christoph,
That's an interesting suggestion. We can look into adding compression
support in the swap code.
Independent of the use case of this patch, is it acceptable to change
the default I/O scheduler of loop devices from mq-deadline into none
(patches 1 and 2 of this series)?
Thanks,
Bart.
