If mem_cgroup_disabled() Then Return

_read_lock() - mark the beginning of an RCU read-side critical section* When synchronize_rcu() is invoked on one CPU while other CPUs* are within RCU read-side critical sections, then the* synchronize_rcu() is guaranteed to block until after all the other

memcg = mem_cgroup_from_task( fetch RCU-protected pointer for dereferencing(* "owner" points to a task that is regarded as the canonical * user/owner of this mm. All of the following must be true in * order for it to be changed: * current == mm->owner * current->mm != mm * new_owner->mm == mm * new_owner->alloc_lock is held))

If Value is more likely to compile time(memcg) Then memcg_memory_event(memcg, event)

803

_read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
