--- Comment #11 from Andrew Turner <Andrew@FreeBSD.org> ---
I see that WORKLIST_INSERT will set ONWORKLIST in wk_state. Is this always
locked? The existence of WORKLIST_INSERT_UNLOCKED seems to imply it's not. =
As
arm64 has a weaker memory model than x86 the ordering of setting this bit a=
nd
adding the item to the list is not guaranteed.
