Subject: linux-next: build warning after merge of the fsinfo tree

Hi all,

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

samples/watch_queue/watch_test.c: In function 'saw_super_change':
samples/watch_queue/watch_test.c:107:21: warning: format '%llx' expects argument of type 'long long unsigned int', but argument 2 has type '__u64' {aka 'long unsigned int'} [-Wformat=]
  107 |  printf("SUPER %08llx change=%u[%s]\n",
      |                ~~~~~^
      |                     |
      |                     long long unsigned int
      |                %08lx
  108 |         s->sb_id, n->subtype, super_subtypes[n->subtype]);
      |         ~~~~~~~~     
      |          |
      |          __u64 {aka long unsigned int}
