[Feature Description]
PSTORE codes has big change in mainline kernel v5.8.7 release version, which also supported saving system crash info to block device.
Fixes and new features for pstore.
This is a pretty big set of changes (relative to past pstore pulls),
but it has been in -next for a while. The biggest change here is the
ability to support a block device as a pstore backend, which has been
desired for a while. A lot of additional fixes and refactorings are
also included, mostly in support of the new features.
