I wonder why my compiler doesn't show this warning.

Anyway, NAK: just removing the variable is the wrong fix - you need to look at
the code more closely.  The actual fix is to pass it to kernel_sendmsg()
instead of 2.

But thanks anyway!  Do you want to respin your patch?

Btw, this should be a 'Fixes: <commit> ("subject")' line and the patch needs
to go to net, not net-next.
