=== Add support for pidfd file descriptors ===
 +
 +
'''Summary:''' Support C/R of pidfd descriptors
 +
 +
There is pidfd_open syscall which allows opening
 +
a special PID file descriptor. A user can send a signal to
 +
the process (pidfd_send_signal syscall), wait for the process
 +
(poll() on pidfd).
 +
 +
At the moment CRIU can't dump processes that have pidfd's opened.
