> this patch series contains at first a patch which adds a check for > IFE_ENCODE and IFE_DECODE when a ife act gets created or updated and adding > handling of these cases only inside the act callback only. > > The second patch use per-cpu counters and move the spinlock around so that > the spinlock is less being held in act callback. > > The last patch use rcu for update parameters and also move the spinlock for > the same purpose as in patch 2. > > Notes: > - There is still a spinlock around for protecting the metalist and a > rw-lock for another list.

I suppose the pointer will be updated, then we don't > have any issue here. Series applied.
