       vm.writesharedcopy
              Page copy for shared page write

               See probe::vm.writesharedcopy(3stap)

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

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

       vm.kmalloc
              Fires when kmalloc is requested

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

       vm.kmemcachealloc
              Fires when kmemcachealloc is requested

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

       vm.kmallocnode
              Fires when kmallocnode is requested

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

       vm.kmemcacheallocnode
              Fires when kmemcacheallocnode is requested

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

       vm.kfree
              Fires when kfree is requested

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

       vm.kmemcachefree
              Fires when kmemcachefree is requested

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