Bit of a nit pick here, but you should try and use the cover letter to 
explain the necessary context and justification for your series. An 
overview of the commits is already included below by b4 or git-send-email.

It would be good to establish if these fixes are all related in some way 
(ie to enable a specific usecase), or if it's just a few random things 
that folks have discovered. Although it's almost always useful for 
maintainers to know how these issues where discovered as it could expose 
a gap in testing.
