Why should we need pstore_block?
1. Most embedded intelligent equipment have no persistent ram, which
increases costs. We perfer to cheaper solutions, like block devices.
In fast, there is already a sample for block device logger in driver
MTD (drivers/mtd/mtdoops.c).

I think you should add a patch for some actual block device using this
new framework to show that it can work. What HW you think would be
using things?

I will try to add a patch. Actually, I have implemented it on allwinner
platform, but unfortunately these codes are unsuitable to submit to
upper stream.

In addition, there is already a sample for pstore/blk on patch 3 of
version 7. It names
blkoops. Blkoops is suitable for most block device as what it need is
just a path of a partition. We can use it to test most of features but
panic.
