Some get_status() methods may allocate data, because not all of the fields in /proc/[pid]/status file have the fixed size. For example, NSpid, which size may vary. Introduce new method free_status() in counterweight for such type get_status() methods. it will be called in case of we go to try_again and need to free allocated data. Also, introduce data parameter for a use in the future. Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: Andrei Vagin <avagin@virtuozzo.com>
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.
