[CRIU] [PATCH v2 00/14] Introduce custom per-task service fds placement

[Kirill Tkhai]

Hi, there is the second version of the patchset.

Changes are in [5/12] (added more comments),
[12/14] (added a handle for very big fd numbers).
Also, [13-14/14] are new. [14/14] is a test,
[13/14] is a dependence (it was already sent in
another pathset).
