sys/sys ktr.h
sys/kern kern_clock.c kern_switch.c
Log:
Clean up unused or poorly utilized KTR values. Remove KTR_FS, KTR_KGDB,
and KTR_IO as they were never used. Remove KTR_CLK since it was only
used for hardclock firing and use KTR_INTR there instead. Remove
KTR_CRITICAL since it was only used for crit enter/exit and use
KTR_CONTENTION instead.
Actually, I thought I had mentioned that KTR_CRITICAL should stay as it is
(well, and the larger thought about doing away with the entire bitmask
concept which no one responded to). critical_enter/exit are not related in
the least to KTR_CONTENTION which is used for MUTEX_PROFILING, nor do they
have anything at all to do with contention of any sort. If you must stick
them somewhere, put them in KTR_SCHED instead. I think scottl@ recently
added support to schedgraph for those traces anyway (though I'm not sure if
they are in his local tree or CVS).
Ah, I misread your email. I see now what you said.
The hardclock trace can probably just be axed entirely as it isn't all that
useful.
Ok, done.
