AFAIK very few people from the community support the idea of having the C/R functionality implemented as the kernel subsystem. > I have seen patches from Pavel about another approach for > checkpointing/restarting but I haven't heard anything about > that during the last months. > > What are the chances to get one of the checkpointing/restarting > implementations included. What is still missing from the one I used? The chances are ... quite high. We implement our C/R code in the userspace and require very few pieces from kernel. So far 2 out of 3 proposed API extensions were merged into -mm tree. > What is the latest state of Pavel's patches? The state right now is - we can dump and restore tasks with any types of memory, open regular files and pipes with its contents. The code is currently under internal review process. We're going to send the public RFC early next week. Then go on with more resources to dump and restore. > Adrian > . >
