[CRIU] [PATCH 0/5] IPC: checkpoint/restore in userspace enhancements

[Stanislav Kinsbursky]

This patch set aimed to provide additional functionality for all IPC objects,
which is required for migration these objects by user-space checkpoint/restore
utils.
The main problem here was impossibility to set up object id. This patch set
solves the problem in two steps:
1) Makes it possible to create new object (shared memory, semaphores set or
messages queue) with ID, equal to passed key.
2) Makes it possible to change existent object key.

The following series consists of:
