If anyone has any objections, please let me know. ------------------ From: Zhongqiu Han [ Upstream commit db6a017c91b774c15b1b890db45981eacfff540e ] The kerneldoc of sugov_iowait_apply() says the IO boost value is increased in sugov_iowait_apply() and, in the same sentence, that it is decreased by the same function. That is self-contradictory, and the first part is wrong: sugov_iowait_apply() only decreases the boost. The boost is actually increased in sugov_iowait_boost(). Fix the comment to name sugov_iowait_boost() as the place where the boost is increased, so it matches the code. No functional change.
