Subject: dn_getsockoptdecnet: move nf_{get/set}sockopt outside sock lock
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a5a3182e50b5be88efd01050ba6f35e2d0aaee03;p=pandora-kernel.git

dn_getsockoptdecnet: move nf_{get/set}sockopt outside sock lock

commit dfec091439bb2acf763497cfc58f2bdfc67c56b7 upstream.

After commit 3f34cfae1238 ("netfilter: on sockopt() acquire sock lock
only in the required scope"), the caller of nf_{get/set}sockopt() must
not hold any lock, but, in such changeset, I forgot to cope with DECnet.

This commit addresses the issue moving the nf call outside the lock,
in the dn_{get,set}sockopt() with the same schema currently used by
ipv4 and ipv6. Also moves the unhandled sockopts of the end of the main
switch statements, to improve code readability.
