46 Mux-locked muxes does not lock the entire parent adapter during the
48 adapter are locked. Mux-locked muxes are mostly interesting if the
50 their tasks. Since the parent adapter is not fully locked during the

87 Mux-locked caveats
90 When using a mux-locked mux, be aware of the following restrictions:
93 If you build a topology with a mux-locked mux being the parent
94 of a parent-locked mux, this might break the expectation from the
95 parent-locked mux that the root adapter is locked during the
100 mux-locked muxes that are not siblings, when there are address
109 but mux-locked muxes do not guarantee that in all topologies.
112 A mux-locked mux cannot be used by a driver for auto-closing
125 Parent-locked muxes
128 Parent-locked muxes lock the parent adapter during the full select-
134 Parent-locked Example

165 This means that accesses to both D2 and D3 are locked out for the full
168 Parent-locked Caveats
171 When using a parent-locked mux, be aware of the following restrictions:
174 If you build a topology with a parent-locked mux being the child
179 This is especially the case if the parent mux is mux-locked, but
180 it may also happen if the parent mux is parent-locked.

291 any point, just as is expected for mux-locked muxes.
293 When D3 or D4 are accessed, everything else is locked out. For D3
