Subject: [PATCH 0/8] Some pstore improvements

Hi pstore maintainers, this is a small series with some improvements
overall. Most of them are minors, but the implicit conversion thing
is a bit more "relevant" in a sense it's more invasive and would fit
more as a "fix".

The code is based on v6.0, and it was tested with multiple compression
algorithms (zstd, deflate, lz4, lzo, 842) and two backends (ramoops and
efi_pstore) - I've used a QEMU UEFI guest and Steam Deck for this goal.

My plan is to also work some ramoops improvements (for example, related
to [0]); they're more complex so it's deferred for a second series,
specific for that.

Reviews and comments are greatly appreciated!
Thanks in advance,

Guilherme
