Another page fault oops this time when 6.11.8 was shutting to boot
6.11.9.
This one is in ext4 -> rbtree and I don't see raid at all this time.
(Soadding ext4 maintainers)
The previous oops occurred in clone_endio from dm_mod.
I note that 9 hours before the oops there was a an ext4 error - in case
it's relevant.
This oops occurred in rb_first+0x13 invoked from
ext4_discard_preallocations+0xc3.
