Hi Pavel. I'm keen to see if we can merge Suspend2's freezer implementation after 2.6.11. Does that conflict with any of your intended changes? If it doesn't, I'll submit a patch for review/merge as quickly as I can.
The main change involves the introduction of a new SYNCTHREAD flag. We use this to avoid deadlocking over processes that are running sys_sync and siblings. Processes that enter those routines get the flag added, and it's removed when they exit the sync routine. We then freeze in four stages: 1) Freeze user space threads without SYNCTHREAD set; 2) Freeze user space threads with SYNCTHREAD set; 3) Run our own sys_sync in case no one else was syncing 4) Freeze kernel space threads without NOFREEZE set. I'd also like to look at your SMP support and see if we can improve compatibility there at the same time. Finally I'd like to merge the support for freezer flags on workqueues.
