I took a quick look at your patch. It seems to be no problem for existing dm-ioband code, but I would suggest you that you had better use checkpatch.pl to check for your coding style. The patch could be applied and compiled successfully. I did a simple test, running fio on each cgroup in 30 seconds simultaneously, and got the following results. w/o range-bw w/ range-bw (min&max-bw settings) cgroup1 331KB/s 102KB/s (100KB) cgroup2 331KB/s 196KB/s (200KB) Do you have any benchmark resutls? I'd be very interested to see it.
