Hi!

> https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master

The relevant part of the log is:

fsmount02.c:56: TFAIL: invalid-flags: fsmount() succeeded unexpectedly (index: 1)

This is another case where new flag was added so the invalid flag value
is not invalid anymore. The test needs to be adjusted if/once the patch
hits mainline.

Ah, very good to know. Adding Mark so he's aware that this is an
expected failure.
