NAME
tapset::memory - systemtap memory tapset

DESCRIPTION
 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
