Subject: [RFC v3 0/3] test driver to analyse vmalloc allocator
Date: Wed, 2 Jan 2019 09:59:21 +0100 [thread overview]
Message-ID: <20190102085924.14145-1-urezki@gmail.com> (raw)
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.
