Subject: mm: vmalloc: use trace_alloc_vmap_area event
Date: Tue, 18 Oct 2022 20:10:50 +0200

This is for debug purpose and is called when an allocation attempt occurs.
This event gives some information about:

- start address of allocated area;
- size that is requested;
- alignment that is required;
- vstart/vend restriction;
- if an allocation fails.
