   34 # Above each of the vop descriptors in lines starting with %%
   35 # is a specification of the locking protocol used by each vop call.
   36 # The first column is the name of the variable, the remaining three
   37 # columns are in, out and error respectively.  The "in" column defines
   38 # the lock state on input, the "out" column defines the state on successful
   39 # return, and the "error" column defines the locking state on error exit.
   40 #
   41 # The locking value can take the following values:
   42 # L: locked; not converted to type of lock.
   43 # A: any lock type.
   44 # S: locked with shared lock.
   45 # E: locked with exclusive lock for this process.
   46 # O: locked with exclusive lock for other process.
   47 # U: unlocked.
   48 # -: not applicable.  vnode does not yet (or no longer) exists.
   49 # =: the same on input and output, may be either L or U.
   50 # X: locked if not nil.
   51 #
   52 # The paramater named "vpp" is assumed to be always used with double
   53 # indirection (**vpp) and that name is hard-coded in vnode_if.awk !
   54 #
   55 # Lines starting with %! specify a pre or post-condition function
   56 # to call before/after the vop call.
   57 #
   58 # If other such parameters are introduced, they have to be added to
   59 # the AWK script at the head of the definition of "add_debug_code()".
