[PATCH 3.18 08/15] mm: slub: fix format mismatches in slab_err() callers

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andrey Ryabinin <a.ryabinin@xxxxxxxxxxx>

commit f6edde9cbe0634e4391b6e421a609ca3f57f6c38 upstream.

Adding __printf(3, 4) to slab_err exposed following:

  mm/slub.c: In function `check_slab':
  mm/slub.c:852:4: warning: format `%u' expects argument of type `unsigned int', but argument 4 has type `const char *' [-Wformat=]
      s->name, page->objects, maxobj);
      ^
  mm/slub.c:852:4: warning: too many arguments for format [-Wformat-extra-args]
  mm/slub.c:857:4: warning: format `%u' expects argument of type `unsigned int', but argument 4 has type `const char *' [-Wformat=]
      s->name, page->inuse, page->objects);
      ^
  mm/slub.c:857:4: warning: too many arguments for format [-Wformat-extra-args]

  mm/slub.c: In function `on_freelist':
  mm/slub.c:905:4: warning: format `%d' expects argument of type `int', but argument 5 has type `long unsigned int' [-Wformat=]
      "should be %d", page->objects, max_objects);

Fix first two warnings by removing redundant s->name.
Fix the last by changing type of max_object from unsigned long to int.
