I can't always remember the return values of these functions, and so I usually jump to the function to read the kernel-doc and see that it doesn't tell me. Then I have to spend more time reading the code to jump to the function that actually tells me the return values. Let's document it here so that we don't all have to spend time digging through the code to understand the return values. Cc: <linux-doc@vger.kernel.org> Signed-off-by:
