- Have kprobes not use copy_from_user() to access kernel addresses,
because kprobes can legitimately poke at bad kernel memory, which
will fault. Copy from user code should never fault in kernel space.
Using probe_mem_read() can handle kernel address space faulting.
- Put back the entries counter in the tracing output that was accidentally
removed.
