Hi, Is it possible to force a flush of the dirty cache in a dm-cache device? I read in the kernel docs[*] that there is a cleaner policy, but it doesn't describe well how to use it. Ideally, I'd like to be able to use `dmsetup message` to issue a flush after suspending the cache to ensure that all dirty data is written to origin and no more data is dirtied before resuming. Is this possible? Thanks Forza [*] https://www.kernel.org/doc/html/v6.5/admin-guide/device-mapper/cache.html
