[ClusterLabs] Error in documentation of resource sets (collocation)?

Hi,


When I read the documentation of the colocating sets of of resources,
the last "note" section reads:


Pay close attention to the order in which resources and sets are listed.
While the colocation dependency for members of any one set is
last-to-first, the colocation dependency for multiple sets is
first-to-last. In the above example, B is colocated with A, but
colocated-set-1 is colocated with colocated-set-2.

But in the example above the config is:

<resource_set id="colocated-set-1" sequential="true">
        <resource_ref id="B"/>
        <resource_ref id="A"/>
</resource_set>


So reading form last-to first inside the resource set would be "A" with
"B", which also correcpondens to the picture above. So the part "B is
colocated with A" seems to be wrong and should be "A is colocated with B"


Mit freundlichen Grüßen,
