Someone has a patch to remove msr-index.h which, in a similar way,
only ended up being exported because of a Kbuild rule.  So I'd imagine
this file would be a candidate for a similar patch.

should include/uapi include header files *unused* in kernel space?

[Robert P. J. Day]

  was perusing the UAPI content in the kernel source, prepping for a
course i'm teaching tomorrow, and just noticed there is a header file:

  $ find . -name mtd-user.h
  ./include/uapi/mtd/mtd-user.h
  $

which appears to be *entirely* unreferenced in the entire kernel code
base (outside of the Kbuild file that refers to it):

  $ grep -r 'mtd-user.h' *
  include/uapi/mtd/Kbuild:header-y += mtd-user.h
  $

does this make any sense? am i missing something here? i would have
thought that if a header file includes content that is wholly used
exclusively in user space, it would be part of a package like
"mtd-devel", or something like that.

  is this just for convenience to keep all the mtd stuff in the same
place?
