My personal preference (which counts for nothing here) is to put
the operators at the start of the continuation like in order to
make it more obvious that it is a continuation.
The netdev rules are particularly problematical for code like:
if (tst(foo, foo2, foo3, ...) && ....... &&
tst2(......) && tst3()) {
baz(....);
where a scan read of the LHS gives the wrong logic.
At least we don't have a coding style that allows very long lnes
an puts } and { on their own lines - leading to:
...
}
while (foo(...) && bar(...) && ..... /* very long line falls off screen */
{
int x;
Is that the top or bottom of a loop?
