2013-11-11lockdep/proc: Fix lock-time avg computationPeter Zijlstra1-1/+1
> kernel/locking/lockdep_proc.c: In function 'seq_lock_time': > >> kernel/locking/lockdep_proc.c:424:23: warning: comparison of distinct pointer types lacks a cast [enabled by default] > > 418 static void seq_lock_time(struct seq_file *m, struct lock_time *lt) > 419 { > 420 seq_printf(m, "%14lu", lt->nr); > 421 seq_time(m, lt->min); > 422 seq_time(m, lt->max); > 423 seq_time(m, lt->total); > > 424 seq_time(m, lt->nr ? do_div(lt->total, lt->nr) : 0); > 425 } My compiler refuses to actually say that; but it looks wrong in that do_div() returns the remainder, not the divisor.
