Subject: mm/vmalloc: extend __find_vmap_area() with one more argument
Date: Tue, 7 Jun 2022 11:34:48 +0200

__find_vmap_area() finds a "vmap_area" based on passed address.  It scan
the specific "vmap_area_root" rb-tree.  Extend the function with one extra
argument, so any tree can be specified where the search has to be done.

There is no functional change as a result of this patch.
