This makes the code cleaner. This helper is made of only two line of self explanational code and not reused anywhere else. And this actually make the compiled object smaller by a bit. bloat-o-meter results on x86_64 of mm/swap_state.o: add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-35 (-35) Function old new delta swap_ra_info.constprop 512 477 -35 Total: Before=8388, After=8353, chg -0.42% Link: https://lkml.kernel.org/r/20221219185840.25441-4-ryncsn@gmail.com Signed-off-by: Kairui Song <kasong@tencent.com> Reviewed-by: "Huang, Ying" <ying.huang@intel.com> Cc: David Hildenbrand <david@redhat.com> Cc: Hugh Dickins <hughd@google.com> Cc: Matthew Wilcox (Oracle) <willy@infradead.org> Cc: Miaohe Lin <linmiaohe@huawei.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
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.
