The fork function in gcc is considered a built in function due to being used by libgcov when building with gnu extensions. Rename fork to sched_process_fork to prevent this conflict. See details:d1c3882392https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82457 Fixes the following error: In file included from progs/bench_local_storage_create.c:6: progs/bench_local_storage_create.c:43:14: error: conflicting types for built-in function 'fork'; expected 'int(void)' [-Werror=builtin-declaration-mismatch] 43 | int BPF_PROG(fork, struct task_struct *parent, struct task_struct *child) | ^~~~ Fixes:cbe9d93d58("selftests/bpf: Add bench for task storage creation") Signed-off-by: James Hilliard <james.hilliard1@gmail.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20230331075848.1642814-1-james.hilliard1@gmail.com
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.
