@ -254,6 +254,32 @@ you will have done run-time testing specific to your change, but at a
minimum, your changes should survive an ``allyesconfig`` and an
``allmodconfig`` build without new warnings or failures.
Q: How do I post corresponding changes to user space components?
----------------------------------------------------------------
A: User space code exercising kernel features should be posted
alongside kernel patches. This gives reviewers a chance to see
how any new interface is used and how well it works.
When user space tools reside in the kernel repo itself all changes
should generally come as one series. If series becomes too large
or the user space project is not reviewed on netdev include a link
to a public repo where user space patches can be seen.
In case user space tooling lives in a separate repository but is
reviewed on netdev (e.g. patches to `iproute2` tools) kernel and
user space patches should form separate series (threads) when posted
to the mailing list, e.g.::
[PATCH net-next 0/3] net: some feature cover letter
└─ [PATCH net-next 1/3] net: some feature prep
└─ [PATCH net-next 2/3] net: some feature do it
└─ [PATCH net-next 3/3] selftest: net: some feature
[PATCH iproute2-next] ip: add support for some feature
Posting as one thread is discouraged because it confuses patchwork
(as of patchwork 2.2.2).
Q: Any other tips to help ensure my net/net-next patch gets OK'd?
-----------------------------------------------------------------
A: Attention to detail. Re-read your own work as if you were the
