Discussing the latest breakage of the linux-next tree, Stephen Rothwell noted that the problem went unnoticed due to the arm tree not currently being included, "this is why I would have liked you to participate in the linux-next tree ...". Arm maintainer Russell King questioned the usefulness, saying, "linux-next will not give me anything which -mm isn't giving me. As I said in the discussion, linux-next value is _very_ small for me. Sorry but true." Several stepped in to offer some reasons that the linux-next tree is useful.
Andrew Morton noted, "putting arm into linux-next means that Stephen (and git) handle the merges rather than having me (and not-git) do it. Which helps me. I expect that linux-next will get a lot more cross-compilation testing than -mm. Which helps you." Greg KH added, "getting your stuff into linux-next would provide a public place for others to base off of, making it easier for them to send patches to you ensuring that they apply properly. Which in the end, will help others be able to contribute easier, and help you by getting patches you do not need to rebase yourself." Stephen Rothwell summarized the advantages for a maintainer:
"5 times a week your tree gets merged with lots of other code destined for Linus' next release. From this you get to find out about things in other trees that clash with yours. This tree gets built on several architectures for several configs (including arm). So you find out if other trees will break yours. I am happy to build more (basically all) the arm configs as I have offered before."
