[CRIU] [PATCH 00/14] mount: move mntinfo_tree to the namespace structure

[Andrey Vagin]

We are going to support nested mount namespace. Each mount namespace has
own tree of mounts, so we need to save root on the namespace structure.

Each time when we want to access a file, we need to determing its
namespace and collect a proper root.

Andrey Vagin (14):
  mount: return descriptor from mntns_collect_root
  mount: save mount tree for each namespace
  mount: move dump_mnt_namespaces in mount.c
  mount: separate collect_mnt_ns from dump_mnt_ns
  resotre: collect mounts of current mntns
  mount: __lookup_mnt_id returns the first mi if mnt_id == -1
  mount: set nsid for each mount point
  mounts: mntns_collect_root in __open_mountpoint
  irmap: mntns_collect_root in irmap_lookup
  mount: add a function to get a temporary root for mntns
  mount: use per-ns list of mount-points in clean_mnt_ns and free_mnt_ns
  check: collect mounts of the current mntns
  mount: use per-namespace mntinfo_tree
  mount: don't open the same root twise
