Or to put it another way, use a blank line before the
first or only label in an error/out block.
I don't find it different then commonly written blocks like:
void foo(void)
{
...;
wind1();
val = func1(...);
if (val) {
printk(...);
goto err_type;
}
wind2();
val = func2(...);
if (val) {
printk(...);
goto err_type2;
}
...
return 0;
err_type2:
unwind2();
err_type:
unwind1();
return -ERR;
}
Yes, you can elide all the blank lines, but using them can
help readability.
