Subject: BUG: core dump in selftest of proc fs

Dear all,

Trying to complete `make kselftest` for the first time, so maybe I'm doing something wrong?

Or we are having a regression in 6.2-rc2 release candidate ...

However, the output of selftest run is:

make[2]: Entering directory '.../linux_torvalds/tools/testing/selftests/proc'
TAP version 13
1..21
# selftests: proc: fd-001-lookup

# /usr/bin/timeout: the monitored command dumped core
# Aborted
not ok 5 selftests: proc: proc-empty-vm # exit=134
# selftests: proc: proc-pid-vm
# proc-pid-vm: proc-pid-vm.c:365: main: Assertion `rv == len' failed.
# /usr/bin/timeout: the monitored command dumped core
# Aborted

Please find attached lshw output, dmesg, config and lsmod.

I am available for further diagnostics.

The platform is Ubuntu 22.10 kinetic kudu on a Lenovo Ideapad 3 15ITL6 laptop.

Kind regards,
Mirsad
