Which ever is more clear. It's up to you. Or do you mean code like
this?
1)
ret = -ENOMEM;
p = kmalloc();
if (!p)
goto err_free_x;
2)
p = kmalloc();
if (!p) {
ret = -ENOMEM;
goto err_free_x;
}
That's also up to the maintainer. People debate which one is cleaner.
I normally do the second one, unless the rest of the file does the first
one. The first one apparently is slightly better assembly on current
GCCs.
