Pat already has a .config for 3.18.1 in testing/. I replaced my .config from my 3.18.0 build with that and it's been running fine on my current 3.18.8 kernel.

According to your list, the 3.14 kernel in Slackware-current is also an LTS kernel.
Your suggestion has no merit without providing some use case where the 3.18 kernel would serve better than the 3.14 kernel. Such a use case should be for the benefit of all, rather than a some specific local enhancement.
I note that there there are use cases where the the 3.18 kernel causes breakage with existing software.

My unreserved apology for an undeserved lashing out.
It was caused by me being unhappy with so many recent threads in this forum being spoiled by unsubstantiated assertions.

Don't worry, you are free of speech even if you are angry.

well, chromium devs say it's not the case: read the bottom (and the title), more precisely comment #85, of

https://code.google.com/p/chromium/i...tail?id=401655

in the normal kernel of -current
Code:
$ grep SECCOMP config-generic-3.14.33 
CONFIG_HAVE_ARCH_SECCOMP_FILTER=y
CONFIG_SECCOMP_FILTER=y
CONFIG_SECCOMP=y
in the kernel of /testing
Code:
$ grep SECCOMP config-generic-3.18.1.x64                   
CONFIG_HAVE_ARCH_SECCOMP_FILTER=y
CONFIG_SECCOMP_FILTER=y
CONFIG_SECCOMP=y

One thing to consider is that this new LTS is not being maintained by Greg K-H himself, but by someone else. While not wanting to infer anything about their maintainers, results have been somewhat mixed in the past. Personally, I tend to restrict myself to kernels maintained by Greg.

I'm not sure whether Linux 3.18 would be a good idea, but by the time Slackware 14.2 is ready, Linux 3.14 is definitely going to be showing its age.

If Pat does ship with a stock kernel newer than 3.14.y, then I hope he'll still leave glibc+headers built against 3.14 (Assuming 3.14 is still the most recent LTS maintained by Greg at that point) so as to allow people who want to stick with it to 'downgrade' safely.

I was wondering about the Chrome/Chromium issue (I had even started writing it into my reply), but it seemed that I was not affected while running older kernels with newer versions of Chrome/Chromium, so I left it out since I couldn't substantiate it. Glad they updated it saying it was a different bug.

@ponce, the same items are in the .config of the 3.14.33 kernel in -current (since I was at work, I just looked at the http://slackbuilds.org/mirror/slackw...33.x64].config and did a Ctrl+F for seccomp).

Code:
CONFIG_HAVE_ARCH_SECCOMP_FILTER=y
CONFIG_SECCOMP_FILTER=y
CONFIG_SECCOMP=y

Greg Kroah-Hartman has released 3.18.9: https://www.kernel.org/pub/linux/ker...angeLog-3.18.9
But you are right, Greg isn't the announced maintainer for the longterm version 3.18 in kernel.org

I tried the latest Chrome and Chromium dev/unstable releases, just to be sure and again, no problems. I would have expected Phoronix to do this minimal check before posting such an article. Frankly it is embarrassing for them. Slashdot made the same mistake but hey, they are slashdot so it is kinda expected.

P.S. I never doubted that some users have hit a big which involves TSYNC in some way but the claim that it is a hard requirement was easily provable as false.

What existing software were you thinking of? One example is possibly Bluez 5, but not only is that unlikely to be in the next release, -current should already have a stack to support it.

I'm surprised that anyone could have any expectations at all of Phoronix.

Bluz 5 May be getting closer at least, they need this for gui support.
