cvs commit: src/sys/kern lwkt_serialize.c src/sys/i386/include atomic.h
dillon 2005/05/25 15:59:20 PDT
DragonFly src repository
Modified files:
sys/kern lwkt_serialize.c
sys/i386/include atomic.h
Log:
Fix a race in the serializer's use of atomic_intr_cond_enter(). When
the procedure call is made the serializer must enter a critical section
and check the bit again before actually sleeping to avoid a race against
wakeup().
