While running LTP hugetlb testing on x86 the following kernel BUG noticed
on running stable-rc 6.3.12-rc1.

Reported-by: Linux Kernel Functional Testing <lkft@xxxxxxxxxx>

Crash log:
=========
[ 54.386939] hugefallocate01 (410): drop_caches: 3
g tests.......

And this worked on 6.3.11 just fine?

Trying to narrow down what would have caused this...

Any chance you can run Linus's tree with thie LTP test as well?

Ah, I can hit this here locally too! Let me bisect...


Have you looked at Patch 9 of this series:

https://lore.kernel.org/stable/2023070416-wow-phrasing-b92c@gregkh/T/#m12068530e846ac8b9668bd83941d82ec3f22ac15

Looks very much related, it also has a note on Backporting.
As I think it could be related, I am sharing this.(But haven't tested anything)

Thanks,
Harshit
