Hello.
This is v4. I think it is ready to go with, unless there are extra requests
or comments.
Changes in v4:
- Since the test can take time, switch to wait_for_completion_timeout()
with HZ sleep interval to prevent triggering of the trace about hung
task;
- Fix clean apply for v4.20 kernel.
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
I think it is ready to go with, unless there are more requests or comments.
Thank you in advance.
