Hi,
Here is the document of dm-band.
Could you please address in the document how the intended use
cases/feature set etc. differs from CFQ2 io priorities?
Thank you for your suggestion, I'll do that step by step.
Thanks,

Filtering decisions are based on init_net's table so far.
P.S.: remove init_net check in inet6_create() to see the effect

The comment about race free view of the set of network
namespaces was a bit hasty. Look (there even can be only
one CPU, as discovered by Alexey Dobriyan and Denis Lunev):
put_net()
if (atomic_dec_and_test(net-refcnt))
/* true */
__put_net(net);
queue_work(...);
/*
* note:
We have INET_MATCH, INET_TW_MATCH and INET6_MATCH to test
sockets and twbuckets for matching, but ipv6 twbuckets are
tested manually.
Here's the INET6_TW_MATCH to help with it.
Since the commit b3652b2dc5ec6ccd946ae9136b30c6babb81305a
[IPV6]: Mischecked tw match in __inet6_check_established.

That is evil, because that means strace can no longer reliably print
flags being used (for example).
Ahhh.

Hi,
Now I report the result of dm-band bandwidth control test I did yesterday.
I've got really good results that dm-band works as I expected. I made
several band-groups on several disk partitions and gave them heavy I/O loads.
