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/vfs/test-fsinfo.c: In function 'dump_fsinfo_generic_statfs':
samples/vfs/test-fsinfo.c:135:30: warning: format '%llu' expects argument of type 'long long unsigned int', but argument 2 has type '__u64' {aka 'long unsigned int'} [-Wformat=]
  135 |  printf("\tbsize        : %llu\n", f->f_bsize);
      |                           ~~~^     ~~~~~~~~~~
      |                              |      |
