As I see it, we need the following changes. utrace: - utrace_control(SINGLESTEP) calls get_user_pages() under spin_lock() ptrace: - stacked VFORK_DONE event, finish ptrace_report_clone(). The fix must be trivial, but every time I am trying to complete this I understand I should do this with a fresh head ;) - PTRACE_SYSEMU/PTRACE_SYSEMU_SINGLESTEP should be simple... - stacked JCTL events. Oh. I hope this will not be too hard to do something simple and "not too buggy" for now. - ptrace_check_attch(). Must be simple, but I am starting to think I have a blind spot here. - simple cleanups, may be more comments. Anything else? Oleg.
