[PATCH] taskdata: Add a function to return the virtual/ mapping data

[PATCH] taskdata: Add a function to return the virtual/ mapping data

[Richard Purdie]

When building an execution task graph, bitbake does resolve virtual/xxx
namespaces into specific providers. This data isn't exported anywhere
however.

This adds a function so that runqueue can at least retrieve this data
which can then be used by the system.
