add HN_UNLOCK(sc) for "break"?
ditto
Already unlocked.
Unlocked.
Why the ifdefs?
I was not so sure whether I could MFC D12174 to 10-stable/11-stable or not, but I definitely want to MFC driver bits to 10-stable/11-stable.
If D12174 goes well, I probably will MFC it to 10-stable/11-stable. I think adding IOCs does not break ABI.
You're correct. Sorry for the false alarm.
