Please go ahead with copying the glibc posix_fallocate() to
the posix_fallocate gnulib module.
It would depend on the fallocate gnulib module, the
latest version of which I'll keep here:
http://www.pixelbeat.org/patches/gnulib-fallocate.diff

There is an outstanding question on that interface here:
https://bugzilla.redhat.com/show_bug.cgi?id=500487
but that shouldn't be blocking addition of the posix_fallocate
module I think.

cheers,
Pádraig.
