Hi,
I've written a new check for missing error codes. It assumes that
most gotos are error paths (which turns out to be a wrong assumption)
but still the results are kind of interesting.
I'm thinking that it maybe should only warn for a few types of things:
1) p = frob();
if (!p) {
p is a pointer and it was assigned from a function. And the function
doesn't return a mix of error pointers and NULL.
2) if (IS_ERR(p)) {
error pointers. Obvious.
3) if (frob()) {
frob() is a function that returns negatives.
4) if (x > y) {
bounds checking
5) when there is a dev_err() after the if statement.
Anything else that indicates an error path?
regards,
dan carpenter
