From: Huaisheng Ye <yehs1@lenovo.com>
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. [1]: https://lkml.org/lkml/2019/1/3/43 [2]: https://lkml.org/lkml/2019/1/9/6
