            James, It appears the sk_data_ready api change you mentioned is already present in 3.15 too. I'll go ahead and open a tracking ticket for 3.16 so we can start collecting mods needed for kernels > 3.14 there.

            I'm working with upstream kernel in this case.

            James, is 3.16 present in any distro yet like Fedora Core or are you working against strictly upstream kernel.org trees?

            vfs_rename changed again and sk_data_ready api changed. I have patches already for those versions. This is when running against a 3.16 kernel.

            We may very well need a ticket for 3.15 soon. I just saw that fc20 jumped versions overnight from 3.14.x to 3.15.x. Have yet to discover if we need anything extra for 3.15 beyond what we already have in flight for 3.14.

            Is this the latest fc20 kernel?

            Perhaps it is time to open a ticket for 3.16 support.

            with the new patch http://review.whamcloud.com/#/c/10995 it's once again possible to do full server builds for 3.14, including ldiskfs. It still requires a bunch of patches in flight and at least one for an ldiskfs patch series for 3.14 that hasn't even been pushed to gerrit yet. I have a working prototype for that on hand, but not exposed publicly yet.
