The patch titled lockdep: print current locks on in_atomic warnings has been removed from the -mm tree. Its filename was lockdep-print-current-locks-on-in_atomic-warnings.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ Subject: lockdep: print current locks on in_atomic warnings From: Peter Zijlstra <a.p.zijlstra@xxxxxxxxx> Add debug_show_held_locks(current) to __might_sleep() and schedule(); this makes finding the offending lock leak easier.
