Subject: [PATCH v3 0/5] Optimize writecache when using pmem as cache

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.
