Name:Adjust all task's events' filters to the new vma

Proto:static void perf_addr_filters_adjust(struct vm_area_struct *vma)

Type:void

Parameter:

TypeParameterName
struct vm_area_struct *vma
7874  If Not (Flags, see mm.h. & VM_EXEC) Then Return
7877  _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
7879  ctx = fetch RCU-protected pointer for dereferencing(perf_event_ctxp[ctxn])
7880  If Not ctx Then Continue
7883  perf_iterate_ctx(ctx, __perf_addr_filters_adjust, vma, true)
7885  _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()
