[CRIU] [PATCH v3 00/16] AutoFS mounts migration support

[Stanislav Kinsburskiy]

This patch set adds suport for AutoFS mount migration, including:
1) Direct mounts
2) Indirect mounts
3) Catatonic mounts

Note: systemd AutoFS logic breaks with this migration, because device value of
new mount differs to the one, which systemd collected, when it was created the
mount. Because of it systemd ignors any requests from kernel.

v3: fixed write pipe end restore, when it was closed.
