Subject[RFC v3 0/3] test driver to analyse vmalloc allocator
Date
Hello.

This is v3.

The first RFC was here: https://lkml.org/lkml/2018/11/13/957
Please have a look there for detailed description and discussion.

Changes in v3:
- Export __vmalloc_node_range() with _GPL-only prefix;
- Add skip cases if the test can not be executed in current environment.
That is kselftest framework requirement.

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

Appreciate your comments and feedback, so please RFC v3.

Thank you.

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
