Subject: [PATCH v7 00/18] pstore: mtd: support crash log to block and mtd device

Hi!

Well, I guess I spoke too soon. :) Here is v7. Hopefully this is
it. WeiXiong, can you test this and make sure you're happy with the
results?

Take care!

-Kees

v7:
- more renamings in the exported APIs and structs
- fix mtd build
- replace psblk_blkdev_info with passing in a struct to fill
- consolidate bdev opening/checking
- rename psblk_device -> pstore_device_info
- kerndoc for pstore_blk_get_config
- fix hunks in wrong patch
- add missing "static"s for local functions (0day)
