Modified files:
sys/kern kern_mutex.c
sys/sys mutex.h
Log:
- Add a new flag MTX_QUIET that can be passed to the various mtx_*
functions. If this flag is set, then no KTR log messages are issued.
This is useful for blocking excessive logging, such as with the internal
mutex used by the witness code.
- Use MTX_QUIET on all of the mtx_enter/exit operations on the internal
mutex used by the witness code.
- If we are in a panic, don't do witness checks in witness_enter(),
witness_exit(), and witness_try_enter(), just return.
