# Above each of the vop descriptors 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 successful return, and the
|
|
# "error" column defines the locking state on error exit.
|
|
#
|
|
# The locking value can take the following values:
|
|
# L: locked.
|
|
# 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.
|
|
#
|
|
# For operations other than VOP_LOOKUP which require a component name
|
|
# parameter, the flags required for the initial namei() call are listed.
|
|
# Additional flags may be added to the namei() call, but these are required.
