From 34d0ed5ea7a72d5961552fb1758a94f0d3f8f3dc Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Mon, 20 Jan 2014 19:20:13 +0100 Subject: lockdep: Change mark_held_locks() to check hlock->check instead of lockdep_no_validate The __lockdep_no_validate check in mark_held_locks() adds the subtle and (afaics) unnecessary difference between no-validate and check==0. And this looks even more inconsistent because __lock_acquire() skips mark_irqflags()->mark_lock() if !check. Change mark_held_locks() to check hlock->check instead.
