Maybe, maybe not... There's not *that* many of users of either of those.
BTW, what was fchmod(fd, -1) about? It ends up using current ->i_mode,
but that's not only a Linuxism, it's an undocumented one... Old one,
too - 0.99.14v, AFAICS. Looking around on google gave no results (including
usenet search) and there's no changelog for that revision on kernel.org,
AFAICS...
