kbuild bot reported against an intermediate RT patch that the build fails with: > In file included from include/linux/completion.h:12:0, > from include/linux/rcupdate_wait.h:10, > from kernel/rcu/srcutiny.c:27: > kernel/rcu/srcutiny.c: In function 'srcu_drive_gp': > >> include/linux/swait.h:172:7: error: implicit declaration of function '___wait_is_interruptible'; did you mean '__swait_event_interruptible'? > if (___wait_is_interruptible(state) && __int) { \ That error vanishes a few patches later (in the RT queue) because wait.h is then pulled in by other means. It does not seem to surface on !RT. I think that swait should include a header file for a function/macro (___wait_is_interruptible()) it is using.

README
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. See Documentation/00-INDEX for a list of what is contained in each file. 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.
