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.
