--- Comment #4 from Bryan Drewery <bdrewery at FreeBSD.org> ---
Kib had some feedback on the assert:

1. We should also add it (and the interrupt check) to uma_zalloc_arg() (through
1 inline function)
2. The interrupt assert may be wrong since it is not OK to malloc(9) in an
interrupt, regardless of the flags.

Isilon's internal discussion was that we should add a debug stack output rather
than an assert until all major cases are fixed.
