This is already visible in the diff itself, no need to explain what the
patch does.
Also, please run your commit message through a spellchecker.

We have recently started uploading such documents into
bugzilla.kernel.org in order to have a stable reference source, see
alpine.DEB.2.20.1611082002160.3501@nanos">https://lkml.kernel.org/r/alpine.DEB.2.20.1611082002160.3501@nanos
Please do so too and add the link to the commit message.
Rest looks ok to me.
Thanks.
