Oleg Nesterov 0578a97098 uprobes: Fix UPROBE_SKIP_SSTEP checks in handle_swbp() ... If handle_swbp()->add_utask() fails but UPROBE_SKIP_SSTEP is set, cleanup_ret: path do not restart the insn, this is wrong. Remove this check and add the additional label for can_skip_sstep() = T case. Note also that UPROBE_SKIP_SSTEP can be false positive, we simply can not trust it unless arch_uprobe_skip_sstep() was already called. Also, move another UPROBE_SKIP_SSTEP check before can_skip_sstep() into this helper, this looks more clean and understandable. Note: probably we should rename "skip" to "emulate" and I think that "clear UPROBE_SKIP_SSTEP" should be moved to arch_can_skip.
