The comment for khugepaged_scan_sleep_millisecs incorrectly states the default scan period is 30 seconds. The actual default value in the code is 10000ms (10 seconds). This patch corrects the comment to match the code, preventing potential confusion. The incorrect comment has existed since the feature was first introduced.
