#     Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
#     
#     Pull core signal handling updates from Eric Biederman:
#      "It was observed that a periodic timer in combination with a
#       sufficiently expensive fork could prevent fork from every completing.
#       This contains the changes to remove the need for that restart.
#     
#       This set of changes is split into several parts:
#     
#        - The first part makes PIDTYPE_TGID a proper pid type instead
#          something only for very special cases. The part starts using
#          PIDTYPE_TGID enough so that in __send_signal where signals are
#          actually delivered we know if the signal is being sent to a a group
#          of processes or just a single process.
#     
#        - With that prep work out of the way the logic in fork is modified so
#          that fork logically makes signals received while it is running
#          appear to be received after the fork completes"
#     
#     * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (22 commits)
#       signal: Don't send signals to tasks that don't exist
#       signal: Don't restart fork when signals come in.
#       fork: Have new threads join on-going signal group stops
#       fork: Skip setting TIF_SIGPENDING in ptrace_init_task
#       signal: Add calculate_sigpending()
#       fork: Unconditionally exit if a fatal signal is pending
#       fork: Move and describe why the code examines PIDNS_ADDING
#       signal: Push pid type down into complete_signal.
#       signal: Push pid type down into __send_signal
#       signal: Push pid type down into send_signal
#       signal: Pass pid type into do_send_sig_info
#       signal: Pass pid type into send_sigio_to_task & send_sigurg_to_task
#       signal: Pass pid type into group_send_sig_info
#       signal: Pass pid and pid type into send_sigqueue
#       posix-timers: Noralize good_sigevent
#       signal: Use PIDTYPE_TGID to clearly store where file signals will be sent
#       pid: Implement PIDTYPE_TGID
#       pids: Move the pgrp and session pid pointers from task_struct to signal_struct
#       kvm: Don't open code task_pid in kvm_vcpu_ioctl
#       pids: Compute task_tgid using signal->leader_pid
