[CRIU] [PATCH 0/5] parasite: don't daemonize non-leader threads

[Andrey Vagin]

For dumping thread we need to execute only one command, so its
demonization is overload.

This patch blocks all signals and dumps all thread related parameters in
PARASITE_CMD_INIT_THREAD, then registers are dumped for this thread and
the last step is unblocking thread signals.

This patch simplifies a parasite code, because it removes execution of
commands for threads.

Thanks Pavel for this idea.

Andrey Vagin (5):
  parasite: return ability to execute code in a thread with specified
    pid
  parasite: don't daemonize threads
  parasite: remove code which used for daemonized threads
  parasite: remove struct parasite_thread_ctl
  parasite: restore signal blocking mask on error paths
