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