> update mm_struct->context when a task migrates to another CPU You might be able to do that using rq->prev_mm or rq->active_mm in move_queued_task() and ttwu_remote() functions... Reference : https://elixir.bootlin.com/linux/v5.7.8/source/kernel/sched/core.c#L1472 https://elixir.bootlin.com/linux/v5.7.8/source/kernel/sched/core.c#L2257 ...however, i begin to cringe as I started to write the above. Why? Because it sounds like a hack to me! :-) > update mm_struct->context when a task migrates to another CPU So, again, why do you want to do this? BTW, in the interest of saving time, let us practice 5-Whys (Reference: https://en.wikipedia.org/wiki/Five_whys) and jump straight to the actual use-case / final problem that you are trying to solve ...and work ahead from there. May be there are pre-existing cleaner approaches to your problem that do NOT involve fiddling with the Linux kernel internals. regards CVS _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
