disabled CONFIG_FORCE_NR_CPUS option for 6.9.5 but the trace + panic
still exists. So that one didn't help. I've also been bisecting the
trace but have not finished it yet as the last half dozen builds
produced non-bootable kernels. Anyway, I will continue it soon(ish)
when I have a bit more free

FYI,
I just debugged a strange crash that was caused by my config having
something

ok, so if you don't have any idea where this bug is after those debug
patches, I'll try to find some time to bisect it as a last resort.
Stay tuned.

Hi, Thorsten here, the Linux kernel's regression tracker. Top-posting
for once, to make this easily accessible to everyone.
Ilkka or Steven, what happened to this? This thread looks stalled. I
also was unsuccessful when looking for other threads related to this
report or the culprit. Did it fall

Unfortunately, it doesn't give me any new information. I added one more
BUG on, want to try this? Otherwise, I'm pretty much at a lost. :-/

Can you try this on 6.6-rc1 and see if it gives you any other splats?
Hmm, you can switch it to WARN_ON and that way it may not

Bah, it's still in an RCU callback, which doesn't tell us why a
normal inode is being sent to the trace

yeah, the cache_from_obj tracing bug (without panic) has been
displayed quite some time now - maybe even since 6.7.x or so. I could
try checking a few versions back for this and try bisecting it if I
can find when this started.

Hi Steven,
I took some time and bisected the 6.8.9 - 6.8.10 and git gave the
panic inducing commit:
414fb08628143 (tracefs: Reset permissions on remount if permissions are options)
I reverted that commit to 6.9.2 and now it only serves the trace but
the panic is gone. But I can live with it.
