Linus,
please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/oleg/misc.git ptrace
This starts the Tejun's ptrace/jobctl rework, initial fixes and cleanups. Plus sigprocmask fixes, those which were reviewed/acked.
Oleg Nesterov (19): signal: prepare_signal(SIGCONT) shouldn't play with TIF_SIGPENDING signal: do_signal_stop: Remove the unneeded task_clear_group_stop_pending() signal: Turn SIGNAL_STOP_DEQUEUED into GROUP_STOP_DEQUEUED ptrace: ptrace_check_attach() should not do s/STOPPED/TRACED/ signal: introduce retarget_shared_pending() signal: retarget_shared_pending: consider shared/unblocked signals only signal: retarget_shared_pending: optimize while_each_thread() loop signal: sigprocmask: narrow the scope of ->siglock signal: sigprocmask() should do retarget_shared_pending() x86: signal: handle_signal() should use set_current_blocked() x86: signal: sys_rt_sigreturn() should use set_current_blocked() signal: cleanup sys_rt_sigprocmask() signal: sys_rt_sigtimedwait: simplify the timeout logic signal: introduce do_sigtimedwait() to factor out compat/native code signal: do_sigtimedwait() needs retarget_shared_pending() signal: rename signandsets() to sigandnsets() signal: cleanup sys_sigprocmask() signal: sys_sigprocmask() needs retarget_shared_pending() signal: trivial, fix the "timespec declared inside parameter list" warning
Tejun Heo (22): signal: Fix SIGCONT notification code ptrace: Remove the extra wake_up_state() from ptrace_detach() signal: Remove superflous try_to_freeze() loop in do_signal_stop() ptrace: Kill tracehook_notify_jctl() ptrace: Add @why to ptrace_stop() signal: Fix premature completion of group stop when interfered by ptrace signal: Use GROUP_STOP_PENDING to stop once for a single group stop ptrace: Participate in group stop from ptrace_stop() iff the task is trapping for group stop ptrace: Make do_signal_stop() use ptrace_stop() if the task is being ptraced ptrace: Clean transitions between TASK_STOPPED and TRACED ptrace: Collapse ptrace_untrace() into __ptrace_unlink() ptrace: Always put ptracee into appropriate execution state job control: Don't set group_stop exit_code if re-entering job control stop job control: Small reorganization of wait_consider_task() job control: Fix ptracer wait(2) hang and explain notask_error clearing job control: Allow access to job control events through ptracees job control: Add @for_ptrace to do_notify_parent_cldstop() job control: Job control stop notifications should always go to the real parent job control: Notify the real parent of job control events regardless of ptrace job control: Don't send duplicate job control stop notification while ptraced ptrace: fix signal->wait_chldexit usage in task_clear_group_stop_trapping() job control: reorganize wait_task_stopped()
