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.
