Mikulas Patocka 93de44eb3f dm writecache: implement the "cleaner" policy ... The "flush" or "flush_on_suspend" messages flush the whole cache. However, these flushing methods can take some time and the process is left in an interruptible state during the flush. Implement a "cleaner" option that offers an alternate flushing method. When this option is activated (either by a message or in the constructor arguments), the cache will not promote new writes (however, writes to already cached blocks are promoted, to avoid data corruption due to misordered writes) and it will gradually writeback any cached data. The userspace can then monitor the cleaning process with "dmsetup status". When the number of cached bloks drops to zero, the userspace can unload the dm-writecache target and replace it with dm-linear or other targets.
