I'm on whatever is in F22. gcc -v says

   gcc version 5.1.1 20150618 (Red Hat 5.1.1-4) (GCC)

and the warning looks like so:

  net/mac80211/rate.c: In function ‘rate_control_cap_mask’:
  net/mac80211/rate.c:719:25: warning: ‘sizeof’ on array function
parameter ‘mcs_mask’ will return size of ‘u8 * {aka unsigned char *}’
[-Wsizeof-array-argument]
     for (i = 0; i < sizeof(mcs_mask); i++)
                           ^

(note the lack of warning about the use of an array in the function
definition parameter list - I tried to find if there's any way to
enable such a warning, but couldn't find anything. Maybe my google-fu
is weak, but more probably that just doesn't exist).
