Modified files:
sys/vm vm_fault.c vm_object.c vm_object.h
vnode_pager.c
Log:
- Add a new object flag "OBJ_NEEDSGIANT". We set this flag if the
underlying vnode requires Giant.
- In vm_fault only acquire Giant if the underlying object has NEEDSGIANT
set.
- In vm_object_shadow inherit the NEEDSGIANT flag from the backing object.
