Struct arpreq contains the name of the device. All other places in the
kernel, the define IFNAMSIZ is used to designate its size. But in
if_arp.h, a literal constant is used.
Fixed by explicitly including uapi/linu/if.h, where IFNAMSIZ is defined.
The series also fixes some incorrect indents.
v1 -> v2:
* Include uapi/linux/if.h from if_arp.h
* Added Stephen's t-b

Struct arpreq contains the name of the device. All other places in the
kernel, the define IFNAMSIZ is used to designate its size. But in
if_arp.h, a literal constant is used.
As it could be good reasons to use constants instead of the defines in
include files under uapi, it seems to be OK to use the define here,
without opening a can of worms in user-land.
This because if_arp.h includes netdevice.h, which also uses
IFNAMSIZ. For the distros I have checked, this also holds true for the
use-land side.
The series also fixes some incorrect indents.

Let uapi/linux/if_arp.h include uapi/linux/if.h, where IFNAMSIZ is
defined. Then, use it in this file instead of hard-coded value.
This way, we are using an uapi defined constant, and as such,
user-space should be good.

Reminder for what?
Your patch was applied to the net-next tree right after it was posted,
what more do you want?
I gather that you have no idea what tree was appropriate for your change
and therefore where your should check to see if it was applied or not.

Oh, my bad then. Was expecting review comments or an "Applied, thanks". Will check the respective tree next time. No need for the v2 then I assume.
