This is the start of the stable review cycle for the 4.14.4 release. There are 95 patches in this series, all will be posted as a response to this one. If anyone has any issues with these being applied, please let me know.
Responses should be made by Wed Dec 6 16:00:27 UTC 2017. Anything received after that time might be too late.
The whole patch series can be found in one patch at: kernel.org/pub/linux/kernel/v4.x/stable-review/patch-4.14.4-rc1.gz or in the git tree and branch at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git linux-4.14.y and the diffstat can be found below.

Compiled, booted and ran the following package unit tests without regressions on x86_64
boringssl : go test target:0/0/5764/5764/5764 PASS ssl_test : 10 pass crypto_test : 28 pass e2fsprogs: make check : 340 pass sqlite make test : 143914 pass drm make check : 15 pass modetest, drmdevice : pass alsa-lib make check : 2 pass bluez make check : 25 pass libusb stress : 4 pass
How do the above tests stress the kernel?
Depends entirely on the package in question.
Sure, of completely no surprise a lot of package unit tests don’t really do much that’s particularly interesting save to the package itself.
Then why run those tests? Like sqlite, what kernel functionality does that exercise that ltp does not?
There are sometimes an interesting subset that drives some amount of work in kernel. That’s the useful stuff.
Is that true with the above list? If so, why are those types of tests not part of any kernel test suite that I have seen before?
Take bluez, and it’s use of CONFIG_CRYPTO_USER_API.
Nice, does that cover things that is not in LTP? Should those tests be added to LTP?
Aren't they just verifications that the source code in the package is correct?
So if there’s some useful subset, that’s what I’m looking for.
I guess it proves something, but have you ever seen the above regress in _any_ kernel release?
Past regressions make for a good test.
You are testing past regressions of the userspace code, not the kernel here. Why do I care about that? :)
Don't fall down the trap of running code for the sake of running code (i.e. like that web site that starts with a P) that doesn't actually test anything that actually matters.
