Currently the protection lookup tables in sd_prot_flag_mask() and sd_prot_op() are declared as non-static. As such, they will be rebuilt for each respective function call. Optimise by making them static. This saves ~100B object code for sd.c: Before: text data bss dec hex filename 25403 1024 16 26443 674b drivers/scsi/sd.o After: text data bss dec hex filename 25299 1024 16 26339 66e3 drivers/scsi/sd.o In addition, since those same functions are declared in sd.h, but each are only referenced in sd.c, relocate them to that same c file. The inline specifier is dropped also, since gcc should be able to make the decision to inline.

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.
