Is this for Ubuntu15? My current kernel is 3.19.0-30.

Comment by Cory Spitz [ 19/Oct/15 ]

James, no this is for the vanilla kernel.org 3.18 LTS, which is now at 3.18.22. We should figure out a good way to handle support for similar kernels so that we don't have a plethora of patches in ldiskfs/kernel_patches.

Can we/should we assign this ticket to Wally? He can add test framework results of runs to Maloo
I'm assuming that we can agree to start landing support for LTS kernels if the work is done, but maybe we want to think longer about that.

All the non ldiskfs patches have landed. Frank do you plan to drop the ldiskfs patch?

Comment by Frank Zago (Inactive) [ 11/Aug/16 ]

Yes, we can close this ticket and abandon ttp://review.whamcloud.com/16861. I don't have the rights to do it so an admin has to do both.
