Commit 63159f5dcc ("uapi: Use __kernel_long_t in struct mq_attr")
changed the types from long to __kernel_long_t, but didn't add a
linux/types.h include. Code that tries to include this header directly
breaks:
/usr/include/linux/mqueue.h:26:2: error: unknown type name '__kernel_long_t'
__kernel_long_t mq_flags; /* message queue flags */
This also upsets configure tests for this header:
checking linux/mqueue.h usability... no
checking linux/mqueue.h presence... yes
configure: WARNING: linux/mqueue.h: present but cannot be compiled
configure: WARNING: linux/mqueue.h: check for missing prerequisite headers?
configure: WARNING: linux/mqueue.h: see the Autoconf documentation
configure: WARNING: linux/mqueue.h: section "Present But Cannot Be Compiled"
configure: WARNING: linux/mqueue.h: proceeding with the compiler's result
checking for linux/mqueue.h... no

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
