[dm-devel] Hibernate/Resume and dm-cache, dm-writeboost...

[Akira Hayakawa]

Hi, I am the developer of DM-Writeboost.

I am not sure what the problem is. Is the problem caching driver
may update the underlying devices before resume?

If so, stopping daemons will do by sending the driver these messages
- allow_writeback 0
- enable_writeback_modulator 0
- update_record_interval 0
The first two stops writeback and the third one stops periodical
update of the superblock sector.

btw, DM-Writeboost isn't in LVM family yet so this problem won't happen
at the moment however, I doesn't mean I can be unaware. Thanks.
