[CRIU] [PATCH 0/6] A few fixes to c/r a docker container with a console

[Andrei Vagin]

From: Andrei Vagin <avagin at virtuozzo.com>

runc creates a pty pair from a container devpts, then bind-mounts
the slave into /dev/console and handles the master externally.

This series solve there problems:
* notify about abandoned master pty-s via rpc
* restore bind-mounted slave pty-s
* create a detached mount when a temporary directory can't be created

https://github.com/opencontainers/runc/issues/1202

Andrei Vagin (6):
  tty: notify about orphan tty-s via rpc
  fdstore: add a storage for file descriptors
  tty: split pty_open_ptmx_index()
  mount: create a slave pty if it has to be bind-mounted to somewhere
  mount: clone a mount namespace to open a detached mount
  zdtm: check a case when a slave pty is mounted to somewhere
