I'd like to understand how patches that don't even compile can be
"tested"?

net/unix/af_unix.c: In function ‘unix_dgram_writable’:
net/unix/af_unix.c:2480:3: error: ‘other_full’ undeclared (first use in this function)
net/unix/af_unix.c:2480:3: note: each undeclared identifier is reported only once for each function it appears in

Could you explain how that works, I'm having a hard time understanding
this?

Also please address Hannes's feedback, thanks.
