And a new tm file of debugfs is created for only dumping tm info. Unlike previous debugfs commands, to dump each tm information, user needs to enter two commands now. The first command writes parameters to tm and the second command reads info from tm. For examples, to dump tm info of priority 0, user needs to enter follow two commands: 1. echo dump priority 0 > tm 2. cat tm The reason for adding new tm file is because we accepted Jakub Kicinski's opinion as link https://lkml.org/lkml/2020/9/29/2101. And in order to avoid generating too many files, we implement write ops to allow user to input parameters. However, If there are two or more users concurrently write parameters to tm, parameters of the latest command will overwrite previous commands, this concurrency problem will confuse users, but now there is no good method to fix it.
