The scheduler added NEED_RESCHED_LAZY scheduling. Record this state as
part of trace flags and expose it in the need_resched field.
Record and expose NEED_RESCHED_LAZY.

Is resistance futile?
I can switch it over to "both" if that's what you meant.

Actually, on Monday, can you send me a v4 with this fix?
I just realized that this patch depends on both my branch (which I'm still
waiting for Linus to pull) and the code that is already in Linus's tree.
Once Linus pulls my branch, I'll apply this on that merge commit. But that
will not be until next week.
Thanks,

Yeah, but I can't do anything with it until Linus pulls in my branch. And I
did the pull request on Wednesday. Would have been earlier, but some people
sent me some bug fixes, so I decided to add them on top. But that required
the normal testing and pushing to linux-next, and waiting a few days.
