There is no reason to believe that a kernel-based version would be
significantly faster or smaller than a user-space version.
cat >> repeat.c
#include <stdio.h>
int main(int argc, char **argv)
{
if (argc != 2) {
fprintf(stderr, "Usage: repeat [text]\n");
exit(1);
}
while(1)
printf("%s", argv[1]);
exit(0);
}
[dmiller@mothra dmiller]$ gcc repeat.c -o repeat
[dmiller@mothra dmiller]$ strip repeat
[dmiller@mothra dmiller]$ ls -l repeat
-rwxrwxr-x 1 dmiller dmiller 2876 Dec 26 09:36 repeat
Surely that wasn't worth all the whinging.
