39 1.13 fvdl # Above each of the vop descriptors is a specification of the locking
40 1.13 fvdl # protocol used by each vop call. The first column is the name of
41 1.13 fvdl # the variable, the remaining three columns are in, out and error
42 1.13 fvdl # respectively. The "in" column defines the lock state on input,
43 1.13 fvdl # the "out" column defines the state on succesful return, and the
44 1.13 fvdl # "error" column defines the locking state on error exit.
45 1.13 fvdl #
46 1.13 fvdl # The locking value can take the following values:
47 1.13 fvdl # L: locked.
48 1.13 fvdl # U: unlocked/
49 1.13 fvdl # -: not applicable. vnode does not yet (or no longer) exists.
50 1.13 fvdl # =: the same on input and output, may be either L or U.
51 1.13 fvdl # X: locked if not nil.

61 1.13 fvdl #
62 1.13 fvdl # XXX - the lookup locking protocol defies simple description and depends
63 1.13 fvdl # on the flags and operation fields in the (cnp) structure. Note
64 1.13 fvdl # especially that *vpp may equal dvp and both may be locked.
65 1.16 sommerfe #
66 1.16 sommerfe # More details:
67 1.20 wrstuden # There are three types of lookups: ".", ".." (ISDOTDOT), and other.
68 1.20 wrstuden # On successful lookup of ".", a reference is added to dvp, and it
69 1.20 wrstuden # is returned in *vpp.
70 1.20 wrstuden # To look up ISDOTDOT, dvp is unlocked, the ".." node is locked, and
71 1.20 wrstuden # then dvp is relocked iff LOCKPARENT is set and this is the last
72 1.20 wrstuden # component name (ISLASTCN set). This preserves the
73 1.20 wrstuden # protocol of always locking nodes from root ("/") downward and
74 1.20 wrstuden # prevents deadlock.
75 1.20 wrstuden # Other lookups find the named node (creating the vnode if needed) and
76 1.20 wrstuden # return it, locked, in *vpp.
77 1.20 wrstuden # For non-"." lookups, if LOCKPARENT is not set or this was not the
78 1.20 wrstuden # last component name, dvp is returned unlocked on a successful
79 1.20 wrstuden # lookup.
80 1.20 wrstuden # On failure, *vpp is NULL, and *dvp is left locked. If there was
81 1.22 wrstuden # an error re-locking dvp (for instance in the ISDOTDOT case),
82 1.22 wrstuden # the error is returned with PDIRUNLOCK set.
83 1.16 sommerfe #
84 1.16 sommerfe # *vpp is always locked on return if the operation succeeds.
85 1.16 sommerfe # typically, if *vpp == dvp, you need to release twice, but unlock once.
86 1.16 sommerfe #
87 1.20 wrstuden # The PDIRUNLOCK flag is set when dvp is unlocked in the lookup routine.
88 1.20 wrstuden # It signals the caller that dvp's lock state changed. It will
89 1.20 wrstuden # be set on exit if either a successful lookup unlocked the
90 1.20 wrstuden # parrent, or there was an error re-locking dvp in the ISDOTDOT case.
