We use the same dumping and restoring mechanism for anon private and anon shared memory. Because of this we can implement manual deduplication of shared anon memory the same way we do it with private anonymous memory. Also we need to rename pid parameter of cr_dedup_one_pagemap to id because now we can pass either pid or shmid there and the actual meaning depends on flags: PR_TASK is for pid, PR_SHMEM is for shmid.

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.
