Oh, I added the comment to patch 5/9 since it fits better there (sorry
that I forgot to mention this). Now the kerneldoc section reads:
+ * @mapped: whether the vm area is mapped, each binder instance is
+ * allowed a single mapping throughout its lifetime
... and the vma check now has the following comment:
+ /* ensure the vma corresponds to the binder mapping */
+ if (vma && !binder_alloc_is_mapped(alloc))
goto err_invalid_vma;
This was the feedback right?
