Switch from BIT(0) to (1UL << 0). First, there are already two different forms used in the header, so there's no need to add a third. Second, the BIT() macros is kernel internal and afaict not actually exposed to userspace. Maybe there's some magic there I'm missing but it definitely causes issues when compiling a program that tries to use SECCOMP_USER_NOTIF_FLAG_CONTINUE. It currently fails in the following way: # github.com/lxc/lxd/lxd /usr/bin/ld: $WORK/b001/_x003.o: in function `__do_user_notification_continue': lxd/main_checkfeature.go:240: undefined reference to `BIT' collect2: error: ld returned 1 exit status Switching to (1UL << 0) should prevent that and is more in line what is already done in the rest of the header.

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.
