Hackers, what does hitting the following assert in vmspace_fork() imply? 3101 <http://fxr.watson.org/fxr/source/vm/vm_map.c#L3101>; new_map = &vm2 <http://fxr.watson.org/fxr/ident?im=3;i=vm2>->vm_map <http://fxr.watson.org/fxr/ident?im=3;i=vm_map>; 3102 <http://fxr.watson.org/fxr/source/vm/vm_map.c#L3102>; locked <http://fxr.watson.org/fxr/ident?im=3;i=locked>; = vm_map_trylock <http://fxr.watson.org/fxr/ident?im=3;i=vm_map_trylock>(new_map); */* trylock to silence WITNESS */* 3103 <http://fxr.watson.org/fxr/source/vm/vm_map.c#L3103>; KASSERT <http://fxr.watson.org/fxr/ident?im=3;i=KASSERT>(locked <http://fxr.watson.org/fxr/ident?im=3;i=locked>, (*"vmspace_fork: lock failed"*)); I am hitting the assert in line 3103 and it seems like the assumption is that the trylock will always get the lock? -vijay
