That doesn't sound like a "level". printk has levels. If you ask for "level 3" messages, you get messages from levels 0, 1, 2, and 3. These seem like "types" or "groups" or something. > + // enable all messages in file with 0x01 level bitmask > + nullarbor:~ # echo -n 'file foo.c level 0x01 +p' > > + <debugfs>/dynamic_debug/control
