PRIu64 is defined in user space to match libc's uint64_t definition.
However, gpioevent_data structure in the kernel is defined using the
kernel's own __u64 type.
gpio-event-mon.c: In function ‘monitor_device’:
gpio-event-mon.c:102:19: warning: format ‘%lu’ expects argument of type
‘long unsigned int’, but argument 3 has type ‘__u64 {aka long long
unsigned int}’ [-Wformat=]
fprintf(stdout, "GPIO EVENT %" PRIu64 ": ", event.timestamp);
^~~~~~~~~~~~~~
LD /tmp/kselftest/gpiogpio-event-mon-in.o
LINK /tmp/kselftest/gpiogpio-event-mon
Fix is to replace PRIu64 with llu, which we know is what the kernel uses
for __u64.

README
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.
