[PATCH 0/7] Add basic trace events for vmap/vmalloc

["Uladzislau Rezki (Sony)" <urezki@gmail.com>]

1. This small series add some basic trace events for the vmap/vmalloc code. 
Since currently we are lack of any, sometimes it is hard to start debuging
a vmap code if an issue is reported or occured.

For example https://lore.kernel.org/linux-mm/Y0p8BZIiDXLQbde%2F@pc636/T/

2. The latest patch adds two reviewers for vmalloc code.

Uladzislau Rezki (Sony) (7):
  mm: vmap: Add alloc_vmap_area trace event
  mm: vmap: Add purge_vmap_area_lazy trace event
  mm: vmap: Add free_vmap_area_noflush trace event
  mm/vmalloc: Use a trace_alloc_vmap_area event
  mm/vmalloc: Use a trace_purge_vmap_area_lazy event
  mm/vmalloc: Use a trace_free_vmap_area_noflush event
  vmalloc: Add reviewers for vmalloc code
