In the v5.4 merge window, a cleanup patch from Al Viro conflicted with my rework of the compat handling for sg.c read(). Linus Torvalds did a correct merge but pointed out that the resulting code is still unsatisfactory. I later noticed that the sg_new_read() function still gets the compat mode wrong, when the 'count' argument is large enough to pass a compat_sg_io_hdr object, but not a nativ sg_io_hdr. To address both of these, move the definition of compat_sg_io_hdr into a scsi/sg.h to make it visible to sg.c and rewrite the logic for reading req_pack_id as well as the size check to a simpler version that gets the expected results.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
