Log:
Massive sync with HEAD:
- Instead of direct manipulation on queue and worklist mutexes, bring macros
for doing this job. This change will make it easy to migrate from using
spinning locks to adaptive ones.
- We don't need spinning locks here. Change them to the adaptive mutexes. This
change should bring no performance decrease, as it did not in my tests.
- Despite several examples in the kernel, the third argument of
sysctl_handle_int is not sizeof the int type you want to export.
- Implement stack protection based on GET_STACK_USAGE() macro.
This fixes system panics possible with complicated netgraph setups
and allows to avoid unneded extra queueing for stack unwrapping.
- Cleanup and tune ng_snd_item() function as it is one of the
most busy netgraph functions.
