Matt, Any chance one of you could put up a set of current patches somewhere? I am trying to make heads and tails of them and it's pretty hard as I haven't been on lse-tech for long and the lse-tech mailing list archives are useless due to the 99 to 1 SPAM ratio ;-( I am quite concerned about that lock your patches put into struct task_struct through struct task_delay_info. Have you done any measurements on how this impacts performance on highly threaded apps on larger system? IMHO it seems to make more sense to use something like Jack's proposed task_notifier code to lock-less collect the data into task local data structures and then take the data from there and ship off to userland through netlink or similar like you are doing? I am working on modifying Jack's patch to carry task local data and use it for not just accounting but other areas that need optional callbacks (optional in the sense that it's a feature that can be enabled or disabled). Looking at Shailabh's delayacct_blkio() changes it seems that it would be really easy to fit those into that framework. Guess I should post some of this code .....
