yes, plain ol' fallocate(2), I think:

       #include <linux/falloc.h>

       long fallocate(int fd, int mode, loff_t offset, loff_t len);

but you need a very recent glibc to get it:

http://sourceware.org/bugzilla/show_bug.cgi?id=7083#c1

it'd be great if we could get that into F11...

BTW, ext4, xfs, btrfs, and ocfs2 all support ->fallocate.
