Please read through Thomas' diatribe^W comments on top-posting and HTML
email[*].  I appreciate that it can be frustrating to configure and get
used to, especially in a corporate environment, but it really does help
get your code upstreamed.

That's because they're copying complex structures that don't fit in a
single memory access.

In the future, please give folks a chance to digest and respond before
spinning another version, especially when there is disagreement over which
direction to take.  E.g. the above {get,put}_user() thing is easy to sort
out with a few back-and-forth mails.  Sending v3 prematurely (and v2 for
that matter) means that closing that discussion requires tracking down the
new version and providing the necessary context.  Which, as an aside, is
why trimming mails and bottom-posting is helpful as it allows the scope of
the conversation to be narrowed to the remaining opens.
