Preparation to simplify the review. parse_mountinfo() assumes that: 1. The "err:" block does all the necessary cleanups on failure. This is wrong, see the next patch. 2. We can never skip the mountpoint. This is true, but we are going to change this. s/goto err/goto end/ in the main loop, add the "end:" label which inserts the new mount_info into the list and then checks ret != 0 to figure out whether we need to abort.

criu ==== 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: http://criu.org/Installation * A simple example of usage: http://criu.org/Simple_loop * More sophisticated example with graphical app: http://criu.org/VNC
