He Zhe 3404019d6d printk: Give error on attempt to set log buffer length to over 2G ... [ Upstream commit e6fe3e5b7d ] The current printk() is ready to handle log buffer size up to 2G. Give an explicit error for users who want to use larger log buffer. Also fix printk formatting to show the 2G as a positive number.
