This is an open issue from August.
The reported kernel warning is still seen on linux next and mainline
while running selftests: core: unshare_test.
Linux version: 6.13.0-rc2-next-20241210

I attempted a bisection of the range provided above, and that has landed
on: 611fbeb44a77 ("selftests:core: test coverage for dup_fd() failure
handling in unshare_fd()"), so the underlying issue was probably there
for much longer.
Al, any thoughts on what could trigger this? I'm assuming you had
something in mind when you added the above test?
