| H A D | vmalloc.c | diff f9863be49312aa1f566dca12603e33487965e6a4 Tue Jun 07 04:34:46 CDT 2022 Uladzislau Rezki (Sony) <urezki@gmail.com> mm/vmalloc: extend __alloc_vmap_area() with extra arguments
It implies that __alloc_vmap_area() allocates only from the global vmap
space, therefore a list-head and rb-tree, which represent a free vmap
space, are not passed as parameters to this function and are accessed
directly from this function.
Extend the __alloc_vmap_area() and other dependent functions to have a
possibility to allocate from different trees making an interface common
and not specific.
There is no functional change as a result of this patch.
