Pull pstore updates from Kees Cook:
"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.
- refactor pstore locking for safer module unloading (Kees Cook)
- remove orphaned records from pstorefs when backend unloaded (Kees
Cook)
- refactor dump_oops parameter into max_reason (Pavel Tatashin)
- introduce pstore/zone for common code for contiguous storage
(WeiXiong Liao)
- introduce pstore/blk for block device backend (WeiXiong Liao)
- introduce mtd backend (WeiXiong Liao)"
