gcc does not generate different code for return foo vs bar = foo; goto x;
x: return bar; So convert it all to direct returns for better readability.

Now suppose somebody needs to change locking. He'll have to convert
it back. 

Please take a look at the overall /proc/net/tcp logic. Any locking 
change will be a major change to the code flow of the whole family
of funtions.
