=== 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.
