I can take this as a Linux-6.9-rcX fix if everyone is okay with it.

Pstore now supports multiple backends, the module parameter
pstore.backend varies from 'registered backend' to 'backends that are
allowed to register' and a new entry /sys/module/pstore/loaded_backend
is added to show which pstore backends are loaded at present. Adjust
selftests to match the change
Introduce a /sys/module entry for loaded pstore backends which
provide users and testcases with a standarized interface to retrieve
information on which pstore backends are currently registered.

fs/ps
Currently, pstore supports only one backend open at a time.
Specifically, due to the global variable "psinfo", pstore only accepts
the first registered backend. If a new backend wants to register later,
pstore will simply reject it and return an error. This design forced us
to close existing backen
This is the 4th version of the patch set. In this patchset we aim to add
pstore multi-backend support then user can register more than one pstore
backend.
Changes in v4:
- Replace all rcu_read_lock with mutex
- Move bif_oops_buf, max_compressed_size and pstore_dumper into
pstore_info_list
- add

Add ability to parse multiple files. Additionally add the
ability to parse all results in the KUnit debugfs repository.
How to parse multiple files:
./tools/testing/kunit/kunit.py parse results.log results2.log

Skip instead of failing when prerequisite conditions aren't fulfilled,
such as invalid xstate values etc. This patch would make the tests show
as skip when run by:
make -C tools/testing/selftest/ TARGETS=x86 run_tests

# timeout set to 45

# # xstate cpuid: inv
Conform the layout, informational and status messages to TAP. No
functional change is intended other than the layout of output messages.

This patch sets network_header and inner_network_header to their respective

inner_network_header later on in GRO. network_header is already set in
