Huh, I meant to properly fix this (broken already in mainline) comment, but I only managed to do that (hopefully) in next patch. :/ However, this surely needs to be fixed here. It's tracking the sum of all tasks' (across CPUs) bandwidth admitted on the system, so that's why it's called dl_total_bw. Incremented when a task passes sched_setattr() and decremented when it leaves the system or changes scheduling class. Does it make a bit more sense? Would you still prefer a different name?
