[CRIU] [PATCH v3 0/6] Restore of "/proc/self/ns/net" fixes

[Kirill Tkhai]

Hi,

here is the third version of fixes of restore opened "/proc/pid/ns/net" files.

Patches 1/6 and 2/6 are new. They allow to add CLONE_VM flag to clone()
in create_user_ns_hierarhy_fn() to keep in consistent state open files
and modifications of memory made by helper with parent task.

v3: Execute create_user_ns_hierarhy_fn() in CLONE_VM environment
v2: Rebased on fresh criu-dev. Added comment.
