Subject: [RFC PATCH v2 0/4] uprobes: return probe implementation

There are RFC uretprobes implementation. I'd be grateful for review.

  RFCv1: https://lkml.org/lkml/2012/12/21/133

I've intentionally removed the retprobe bypass logic, it requires 
a bit more work.

not fixed since last prior RFC review:
  unify xol_get_trampoline_slot() and xol_take_insn_slot()
  protect uprobe in prepare_uretprobe()

v2 changes:
  introduced rp_handler(), get rid of return_consumers
  get rid of uretprobe_[un]register()
  introduced arch_uretprobe_get_sp()
  removed uprobe_task->doomed, kill task immediately
  fix arch_uretprobe_hijack_return_addr()'s returns
  address the v1 minor issues

thanks,

Anton Arapov (5):
  uretprobes/x86: hijack return address
  uretprobes: trampoline implementation
  uretprobes: return probe entry, prepare uretprobe
  uretprobes: invoke return probe handlers
