646Allocates or freed disk space according to the C<$mode> argument. See the

649C<$mode> can currently be C<0> or C<IO::AIO::FALLOC_FL_KEEP_SIZE>

653The file system block size used by C<fallocate> is presumably the
654C<f_bsize> returned by C<statvfs>.

656If C<fallocate> isn't available or cannot be emulated (currently no
657emulation will be attempted), passes C<-1> and sets C<$!> to C<ENOSYS>.
