Hello,

These patches are related to a recently queued series [1] that fixes the
same bugs in normal code.  That series finishes with a patch that would
have exposed the BPF bugs, but luckily it won't get merged until v6.18.

I don't know enough about BPF to verify that it emits the correct code
now, so any pointers are welcome.
