This patch set could be used for dm-writecache when use persistent
memory as cache data device.
Patch 1 and 2 go towards removing unused parameter and codes which
actually doesn't really work.
Patch 3 and 4 are targeted at solving problem fn ctr failed to work
due to invalid magic or version, which is caused by the super block
of pmem has messy data stored.
Patch 5 is used for getting the status of seq_count.
Changes Since v2:
- seq_count is important for flush operations, output it within status
for debugging and analyzing code behavior.
