Modified files:
sys/kern vfs_vnops.c
Log:
- Don't acquire the vnode interlock in _vn_lock() unless no lock type
is requested. Handle this case specially before the while loop.
- Use the held vnode lock to check for VI_DOOMED. The vnode lock and
interlock must both be held to set VI_DOOMED so either one held, even
shared, is sufficient to check it.
