What I do for my trees is that I actually merge the '-fixes' branch (that is scheduled to go to Linus in the 'current' cycle) into my for-next branch as well. This has the advantage of (a) getting all the coverage linux-next does (b) seeing any potential merge conflicts early Is this not feasible for other trees? -- Jiri Kosina SUSE Labs
