ifmcstat/rtsol with debug kernel -- "...with 1 sleep inhibitors"

Hi,

I have no clue which chnage it was but running
 	 ifmcstat
with a debug kernel gives more backtraces than information.

Lots of "uma_zalloc_debug: ... with 1 sleep inhibitors"

Can we please fix this before putting more changes on top for the network stack?


I am also still seeing a similar warning with rtsol still:

# rtsol wlan0
Invoking IPv6 network device address event may sleep with 1 sleep inhibitors
