rcu/kvfree: Invoke debug_rcu_bhead_unqueue() after checking bnode->gp_snap
If kvfree_rcu_bulk() sees that the required grace period has failed to elapse, it leaks the memory because readers might still be using it. But in that case, the debug-objects subsystem still marks the relevant structures as having been freed, even though they are instead being leaked. This commit fixes this mismatch by invoking debug_rcu_bhead_unqueue() only when we are actually going to free the objects. Signed-off-by: Zqiang <qiang1.zhang@intel.com> Signed-off-by: Paul E.
