    Patch in this message
    /
    Date
    From
    Subject[patch 01/10] Create instrumentation directory
    Since we already have the Instrumentation menu in
    kernel/Kconfig.instrumentation and instrumentation code all over the
    kernel tree:

    arch/*/oprofile/*.c
    kernel/kprobes.c
    arch/*/kernel/kprobes.c
    kernel/marker.c
    kernel/profile.c
    kernel/lockdep.c
    vm/vmstat.c
    block/blktrace.c

    We could move them to

    instrumentation/
    arch/*/instrumentation/

    Therefore, we could also move the kprobes and marker samples under

    instrumentation/samples/
