[PATCH v4 0/6] selftests: Add futex functional tests

From: Darren Hart
Date: Wed May 13 2015 - 00:08:09 EST

Hi Shuah,

This series begins the process of migrating my futextest tests into kselftest.
I've started with only the functional tests, as the performance and stress may
not be appropriate for kselftest as they stand.

I cleaned up various complaints from checkpatch, but I ignored others that would
require significant rework of the testcases, such as not using volatile and not
creating new typedefs.

Since v1:
Avoid checkpatch errors on 1/5 by:
- combining a later patch which did substantial cleanup.
- removing file-local typedefs and replacing with structs
- correcting all >80 char lines, except for quoted strings and header boiler
plate due to long email addresses

I did *not* make changes for the following:
- Use of new typdefs for types futex_t and atomic_t as they are used throughout
the test suite and I consider them to be worth while.
- Use of volatile as the warning is about use of volatile in kernel code. The
usage in futextest is correct, as an indicator that other threads may modify
the value.
- Adding parentheses around complex defines as it would break one use case and
change the behavior of another.

Since v2:
- Remove trailing newline from selftests/futex/functional/run.sh

Since v3:
- Replace -lpthread in LDFLAGS with -pthread in LDFLAGS and CFLAGS
- Add .gitignore for the target files (compiled tests)
- Resolved bad content encoding header in my patch submission process

The patches will follow, but I'm providing a pull request for your convenience
as well.
