uml: Replace one-element array with zero-element array
To look at users I did:
$ find arch/um/ include/asm-um -name '*.[ch]'|xargs grep -r 'net_kern\.h'
+-l|xargs grep '\<user\>'
Most users just cast user to the appropriate pointer, the remaining ones are
fixed here. In net_kern.c, I'm almost sure that save trick is not needed
anymore, but I've not verified it.
