[CRIU] [PATCH RFC 0/5] Add support of USERNS

[Andrey Vagin]

Known issues:
* PR_SET_MM_* requires the global CAP_SYS_RESOURCE capability,
so restore of USERNS will fail even with these patches
* devpts must be mounted with the newinstance option
* A new root must be bind-mounted before calling pivot_root

Andrey Vagin (6):
  namespaces: take into account USERNS id
  userns: define protobuf messages for uid and gid maps
  criu: add constants about user namespaces
  userns: parse /proc/PID/{u,g}id_map
  userns: restore {uid,gid}_maps
