[PATCH] mm: slub: fix format mismatches in slab_err() callers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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);
