Re: [PATCH 1/2] lttng-modules: Update revision to grab last bugfix releases

[Robert Yang <liezhi.yang@windriver.com>]

Hi Bruce,

Thanks, we are going to update the kernel from 3.10.11 to 3.10.17 for dora
if there is no objections.

Will we use another kernel source repo for dora ? Or just cherry-pick these
commits ?
