Noticed, before I find a time you send a patch, so I replied to it (it's always
better to send a question in public).

Good point. But I'm not sure if it's the same, as QFMT_VFS_OLD is part of kernel
source tree (part of kernel space code) so it makes sense to test it, whereas
libcap v1 and libnuma v1 are just old versions of user space library.
Or am I wrong?
