Andrew Vagin d3cf1c4f2b restore: Wait for userns being prepared before moving into cgroups (v3) 
When user namespace are stepping in we should wait for their preparation
to complete before start using userns daemon (internally the kernel
checks for uids and if uids are not set -EINVAL will be returned
when usersn calls for sendmsg()).

v2: change stages correctly
v3: Wait prepare_userns() before making any calls to usernsd()

CRIU (Checkpoint and Restore in Userspace)

An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.

The project home is at http://criu.org.
