Although the post-increment in macro 'CPU_SET(next++, &cpuset)' seems safe,
the sequencing can raise compile errors, so move the increment outside the
macro. This avoids an error seen using gcc 12.3.0 for mips64el/musl-libc:
In file included from test_lru_map.c:11:
test_lru_map.c: In function 'sched_next_online':
test_lru_map.c:129:29: error: operation on 'next' may be undefined [-Werror=sequence-point]
129 | CPU_SET(next++, &cpuset);

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 reStructuredText 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.
