Your mail client mangles the patch, it should contain original
identation tabs, not spaces. Please see Documentation/email-clients.txt.

Don't send 2 patches as one email. Either send 2 email or merge them
into one patch (if they are similar changes). You'll ease maintainers'
work.

Please see Documentation/SubmittingPatches, chapter 12 to find out how
to sign the patch.

And please don't crosspost to oss-security and LKML - send a separate
email to o-s with a short description of a bug and a link to the LKML
thread. LKML thread is a place to argue and discuss the solution, but
o-s subscribers are probably not interested in such a discussion.

Thanks,
