Modified files:
sys/kern kern_rwlock.c
sys/sys rwlock.h
Log:
Fix some problems with lock profiling in rw locks:
- Adjust lock_profiling stubs semantic in the hard functions in order to be
more accurate and trustable
- As for sx locks, disable shared paths for lock_profiling. Actually,
lock_profiling has a subtle race which makes results caming from shared
paths not completely trustable. A macro stub (LOCK_PROFILING_SHARED) can
be actually used for re-enabling this paths, but is currently intended
for developing use only.
