# 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-codeed 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()".
