Description

tracker for 3.10 kernel support in rhel7

The 3.10 kernel in the rhel7 rc2 image is quite different from the mainline upstream 3.10 in kernel.org. It includes many features from 3.12 and even 3.13 kernels. In general most of the recipe mentioned in LU-4416 for 3.12 kernels is needed in rhel7 too. The only 3.12 patch that isn't needed is http://review.whamcloud.com/9300.

Establishing a separate tracker that will be specific to rhel7 as there are some mods that will only be relevant to the rhel7 kernel, and not 3.12 or later. One example is ldiskfs support. A new patch series specific to rhel7 will be needed.

quite correct. I will add it to the next version of http://review.whamcloud.com/#/c/12289.

It seems lbuild-rhel7 is missing in contrib/lbuild/Makefile.am. We should add it in some patch. Maybe http://review.whamcloud.com/#/c/12289/

[Bob Glossman (Inactive)]

no. as far as I can tell block tunable is still needed. until it can be deleted from old distros I don't think it should be deleted from el7.

[James A Simmons]

Have you considered dropping the block tunable patch?

[Bob Glossman (Inactive)]

James, I will do so as time permits.

[James A Simmons]

That is good news. So it looks like we don't need the quota patch. Will need to look into SuSE12 to see if it is case there.
