       tapset::memory - systemtap memory tapset

DESCRIPTION         top

        This family of probe points is used to probe memory-related
       events.

       vm_fault_contains
              Test return value for page fault reason

              See function::vm_fault_contains(3stap)
               for details.

       vm.pagefault
              Records that a page fault occurred

               See probe::vm.pagefault(3stap)
               for details.

       vm.pagefault.return
              Indicates what type of fault occurred

               See probe::vm.pagefault.return(3stap)
               for details.

       addr_to_node
              Returns which node a given address belongs to within a
              NUMA system

              See function::addr_to_node(3stap)
               for details.

       vm.write_shared
              Attempts at writing to a shared page

               See probe::vm.write_shared(3stap)
               for details.

       vm.write_shared_copy
              Page copy for shared page write

               See probe::vm.write_shared_copy(3stap)
               for details.

       vm.mmap
              Fires when an mmap is requested

               See probe::vm.mmap(3stap)
               for details.

       vm.munmap
              Fires when an munmap is requested

               See probe::vm.munmap(3stap)
               for details.

       vm.brk Fires when a brk is requested (i.e. the heap will be
              resized)

               See probe::vm.brk(3stap)
               for details.

       vm.oom_kill
              Fires when a thread is selected for termination by the OOM
              killer

               See probe::vm.oom_kill(3stap)
               for details.

       vm.kmalloc
              Fires when kmalloc is requested

               See probe::vm.kmalloc(3stap)
               for details.

       vm.kmem_cache_alloc
              Fires when kmem_cache_alloc is requested

               See probe::vm.kmem_cache_alloc(3stap)
               for details.

       vm.kmalloc_node
              Fires when kmalloc_node is requested

               See probe::vm.kmalloc_node(3stap)
               for details.

       vm.kmem_cache_alloc_node
              Fires when kmem_cache_alloc_node is requested

               See probe::vm.kmem_cache_alloc_node(3stap)
               for details.

       vm.kfree
              Fires when kfree is requested

               See probe::vm.kfree(3stap)
               for details.

       vm.kmem_cache_free
              Fires when kmem_cache_free is requested

               See probe::vm.kmem_cache_free(3stap)
               for details.
