[CRIU] [PATCH 0/4] mount: add support of non-root shared mounts (v2)

[Andrey Vagin]

Cyrill found that CRIU are not able to containers with fedora,
where a service is executed in a separate mount namespace.
Here is a mountinfo for one of such services:
65 64 252:0 /vz/private/1 / rw,relatime shared:29 - ext4 /dev/mapper/centos_pcs-root rw,data=ordered
77 65 252:0 /vz/private/1/var/tmp/systemd-httpd.service-XLnJPNc/tmp /var/tmp rw,relatime shared:41 - ext4 /dev/mapper/centos_pcs-root rw,data=ordered

Here is a non-root shared bind-mount and its parent is from the
same shared group. This series adds support for such mounts.

v2: add more comments
