[Andrey Vagin]

signalfd is used for dumping signals.
rt_sigqueueinfo is used for restoring.

http://wiki.criu.org/Pending_signals

v2: Restore private signals
    Collect all extra SIGCHLD from zombies.
    Save in a protobuf format.
v3: Clean up
v4: rework according with the new kernel interface

Andrey Vagin (14):
  zdtm: add a test case for pending signals
  zdtm: check private pending signals
  syscall: add sigqueueinfo, signalfd and pread
  signalfd: define SFD_RAW, SFD_{SHARED,PER_THREAD}_QUEUE_OFFSET
  protobuf: add a new description for saving siginfo-s
  crtools: add a callback to show signal=*.img
  crtools: add image contants for pending signals (v2)
  crtools: dump pending signals (v2)
  crtools: restore pending signals (v2)
  check: check that signalfd with SFD_RAW and sigqueueinfo with
    positive si_code
  cr-restore: read core before forking
  restore: set up a handler for collecting signals from zombies
  restore: collect signals from zombies
  zdtm.sh: add static/sigpending in the default set
