Your mailer appears to have mangled both your signoff and the whitespace in
the patch and it does not apply. However, fixing it does not solve the problem
because of this mysterious bio_kunmap_bvec() that is only referenced by this
driver. Was it accidently added during the addition of sg chaining support?
