Modified files:
sys/kern kern_ktr.c
sys/sys proc.h
Log:
Use a per-thread variable for keeping state when a thread is processing
a KTR log entry. Any KTR requests made while working on an entry are
ignored/discarded to prevent recursion. This is a better fix for the
hack to futz with the CPU mask and call getnanotime() if KTR_LOCK or
KTR_WITNESS was on. It also covers the actual formatting of the log entry
including dumping it to the display which the earlier hacks did not.
