Log Message:
Pull up revision 1.21 (requested by wrstuden in ticket #425):
Change comments around locking. While you _can_ grab vnode locks
as LK_SHARED, the VOP_ code (in all our existing file systems)
was implememted assuming exclusive locking. Use of LK_SHARED
is technically a bug and only works right for uni-processor and
big-lock SMP systems. Our current file systems will blow up
(probably quite subtlely) with LK_SHARED and fine-grained SMP
locking.
