[BUG]
Currently cli/009 test case failed with different exit number:
====== RUN CHECK /home/adam/btrfs-progs/btrfstune --help
usage: btrfstune [options] device
[...]
failed: /home/adam/btrfs-progs/btrfstune --help
test failed for case 009-btrfstune
[CAUSE]
In tune/main.c, we have the following call on usage():
static void print_usage(int ret)
{
usage(&tune_cmd);
exit(ret);
}
However usage() itself would always call exit(1):
void usage(const struct cmd_struct *cmd)
{
usage_command_usagestr(cmd->usagestr, NULL, 0, true, true);
exit(1);
}
This makes prevents any caller of usage() to modify its exit number.
[FIX]
Add a new argument @error for print_usage(), so we can properly return 0
for -h/--help usage.
