Modified files:
sys/sys vnode.h
sys/kern vfs_subr.c
Log:
- Add vop_strategy_pre to validate VOP_STRATEGY locking.
- Disable original vop_strategy lock specification.
- Switch to the new vop_strategy_pre for lock validation.
VOP_STRATEGY requires only that the buf is locked UNLESS the block numbers need
to be translated. There may be other reasons, but as long as the underlying
layer uses a VOP to perform the operations they will be caught later.
