Changes

ZDTM stands for zero-down-time-migration. It's test suite developed for testing how OpenVZ live migration works. We use this test suite for checking how criu does its job. The suite consists of many small atomic tests. Each such test puts a process into some state (opens a file, maps a memory segment, puts data in a pipe, etc.), then asks to be checkpointed and restored. Upon restoring, it checks that the state was preserved (file is still opened, memory is still mapped, pipe contains what was put into it, etc).

The suite consists of many small atomic tests. Each test case creates a process, puts it into some specific state (opens a file, maps a memory segment, puts data in a pipe, etc.), then asks to be checkpointed and restored. Upon restoring, it checks that the state was preserved (file is still opened, memory is still mapped, pipe contains what was put into it, etc).
