include/scsi/scsi.h was always provided by glibc and was never exported from Kernel.
It was only recently added to include/scsi/Kbuild. (In this merge window, was never released)
(see: [9e4f5e29] [SCSI] FC Pass Thru support)

Two questions. 
1. Are we sure this will work. Is the Header fully compatible with glibc's header.
2. What will this do to distor's package managers having the same file in two packages?
   Don't we need a followup patch sent to glibc to remove that Header from there?

James Smart
  What is the new definitions needed in user-mode in scsi.h that is not available in glibc's
supplied header?

(For reference see this patch from 2007: [e629a7dd] do not export /usr/include/scsi in make headers_install)
