Subject: [RFC patch net/next] net: Hoist assigns from if?
Awhile back I posted a script to reformat source code,
similar to Lindent, but able to select in a piecemeal
manner what source code style to convert.
http://lkml.org/lkml/2010/3/24/447
One of the options is to convert code from:
if ((err = function(args)) != NULL) {
to:
err = function(args);
if (err != NULL) {
I ran this script against net/ and get this result:
$ grep -rPl --include=*.[ch] "\bif\s*\(\s*\(" net/ | \
grep -v netfilter | \
xargs ./scripts/cvt_kernel_style.pl -o -convert=hoist_assigns_from_if
and after a little cleanup, compilation verification, etc
I get the diffstat below. Should I post the actual patch?
