I can say that fstatat64() seems popular (called by rm) =20 > in /var/log/messages. *at() can not be MFCed as it would change the native VFS ABI (Roman =20 implemented the FreeBSD side of *at() calls to be able to emulate the =20 linux *at() calls). As you noticed, this is a major point in 2.6.16 emulation. Another thing which is in current but AFAIK not in stable is the brand =20 detection stuff, but I think this is not so critical to have in =20 RELENG_7. Other changes may or may not be MFCable, but AFAIK nobody took the =20 time to compare RELENG_7 with CURRENT and had a careful look at the =20 differences. Anyway, as *at is a major part and can not be MFCed, =20 2.6.16 + linux base f8 is not a supported combination in RELENG_7. If =20 it works for you feel lucky, if it does not work for you... that's bad =20 luck.
