Make sure we don't pass any trash value here, because
the kernel does copy it explicitly. We allocate the
memory for frame as zero filled but stack segment
is special and zero is not acceptable (we've had
a discussion on LKML if we need a special handling
for zero ss but end up that new kernels need new CRIU
version, upon which all agreed). Finally in
commit 296bbf7e3 I managed to hit exactly
this problem :)

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.
Pages worth starting with are:
- Kernel configuration, compilation, etc
- A simple example of usage
- More sophisticated example with graphical app
