So first off; its not entirely clear that the code as it exists it correct. From a cursory reading of it and surrounding code, there is no actual upper limit on the variable. If I were stupid enough to make a raid with 64 devices I'd get a huge on-stack structure. Since you're touching it; you should check these things. And secondly, refactor the code to not look like dog vomit. You can do more than the absolute minimal patch to make it compile, I'm sure. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
