The following LTP syscalls name_to_handle_at01 and open_by_handle_at01 / 02 tests failed on the Linux next-20241203 tag.

First seen on Linux next-20241204 tag GOOD: Linux next-20241128 tag BAD: Linux next-20241203 tag

I see Christian Brauner's pidfs series getting merged between those tags:

Adding Christian to Cc, he probably already knows what is going on, and if this is a regression in the kernel or a problem in the LTP test case.
