Hi all,

After merging the ext3 tree, today's linux-next build (powerpc
allyesconfig) produced this warning:

samples/fanotify/fs-monitor.c: In function 'handle_notifications':
samples/fanotify/fs-monitor.c:68:36: warning: format '%llx' expects argument of type 'long long unsigned int', but argument 2 has type '__u64' {aka 'long unsigned int'} [-Wformat=]
68 | printf("unexpected FAN MARK: %llx\n", event->mask);
| ~~~^ ~~~~~~~~~~~
| | |
| | __u64 {aka long unsigned int}
| long long unsigned int
| %lx

Introduced by commit

5451093081db ("samples: Add fs error monitoring example")
