I have plans on separate out ptrace related stuff from task_struct so that they're allocate iff they're used which will save some tens of bytes on the task struct, so there at least is a plan to compensate for the added cruft.

I really don't know at this point. I tried to make it share one of the related fields but there needs to be a per-task field which is protected by siglock and there currently isn't any, so...
Thanks.
