Subject[PATCH v2 0/3] pstore: add multi-backend support
Date
I have been steadily working but struggled to find a seamlessly
integrated way to implement tty frontend until Guilherme inspired me
that multi-backend and tty frontend are actually two separate entities.
This submission presents the second iteration of my efforts, listing
notable changes form the v1:

1. pstore.backend no longer acts as "registered backend", but "backends
eligible for registration".

2. drop subdir since it will break user space

3. drop tty frontend since I haven't yet devised a satisfactory
implementation strategy

A heartfelt thank you to Kees and Guilherme for your suggestions.
I firmly believe that a tty frontend is crucial for kdump debugging,
and I am still dedicating effort to develop one. Hope in the future I
can accomplish it with deeper comprehension with tty driver :)
