Subject: [PATCH 0/5] Reduce a vmalloc internal lock contention preparation work 

Hi.

This small serias is a preparation work to implement per-cpu vmalloc
allocation in order to reduce a high internal lock contention. This
series does not introduce any functional changes, it is only about
preparation.

Uladzislau Rezki (Sony) (5):
  mm/vmalloc: Make link_va()/unlink_va() common to different rb_root
  mm/vmalloc: Extend __alloc_vmap_area() with extra arguments
  mm/vmalloc: Initialize VA's list node after unlink
  mm/vmalloc: Extend __find_vmap_area() with one more argument
  lib/test_vmalloc: Switch to prandom_u32()
