Modified files:
sys/sys mutex.h
Log:
- Add a new macro DROP_GIANT_NOSWITCH() that is similar to DROP_GIANT()
except that it uses the MTX_NOSWITCH flag while it releases Giant via
mtx_exit().
- Add a mtx_recursed() primitive. This primitive should only be used on
a mutex owned by the current process. It will return non-zero if the
mutex is recursively owned, or zero otherwise.
- Add two new flags MA_RECURSED and MA_NOTRECURSED that can be used in
conjuction with MA_OWNED to control the assertion checked by mtx_assert().
- Fix some of the KTR tracepoint strings to use %p when displaying the lock
field of a mutex, which is a uintptr_t.
