[RFC v2 0/3] test driver to analyse vmalloc allocator

[Uladzislau Rezki (Sony)]

Hello.

The first RFC was here: https://lkml.org/lkml/2018/11/13/957
Please have a look there for detailed description and discussion.
Here i will just specify what has been done since last RFC:

Changes in v2:
    - Code cleanup to make it more simple;
    - Now __vmalloc_node_range() is exported if CONFIG_TEST_VMALLOC_MODULE=m
    - Integrate vmalloc test suite into tools/testing/selftests/vm

I hope this test suite is more or less ready to go with. Appreciate your
comments and feedback anyway, so please RFC v2.

Thanks.

  vmalloc: export __vmalloc_node_range for CONFIG_TEST_VMALLOC_MODULE
  vmalloc: add test driver to analyse vmalloc allocator
  selftests/vm: add script helper for CONFIG_TEST_VMALLOC_MODULE
