does tinderbox build?

looks like this is guarded by _KERNEL in the original header, we should stick to it just in case in the new one

Makes sense. I will update.

Shift down under _KERNEL.

no, keep it grouped with the rest for consistency but #if defined(_KERNEL) around it

Well, down below are still collection of assertions. I'd rather pull down KASSERT() definitions under _KERNEL. However, that would require additional tinderbox build.

sys/sys/systm.h
148	I do not understand, from the discussion above you all agreed to have the macros under _KERNEL, but there it is not ?

sys/sys/systm.h
148	It is. The ifdef is above at line 134.

sys/sys/systm.h
148	But isn't endif at line 138 ends its scope ?

sys/sys/systm.h
148	You are damn right. So looks like all other kernel related asserts in systm.h aren't covered by _KERNEL. Then I'd suggest to proceed as is, with original patch, where MPASSes were right after KASSERT definition. Then with a new patch tested with separate tinderbox build I will push all kernel related assertions under _KERNEL, all at once.
