[PATCH 1/2] dm-ioband: I/O bandwidth controller v1.12.0: main part
Hi All,
This is the dm-ioband version 1.12.0 release. dm-ioband is an I/O
bandwidth controller implemented as a device-mapper driver and can
control bandwidth on per partition, per user, per process , per
virtual machine (such as KVM or Xen) basis.
The major change of this release is that a new bandwidth control
policy "range-bw" is supported. This policy is developed by Dong-Jae

[PATCH 1/9] I/O bandwidth controller and BIO tracking
Hi all,
These are new releases of dm-ioband and blkio-cgroup. The major
changes of these releases are:
- dm-ioband can be configured through the cgroup interface. The
bandwidth can be assigned on a per cgroup per block device basis.
- The event tracing is supported that helps in debugging and
monitoring dm-ioband.
- A document for blkio-cgroup is available at

[PATCH 1/9] I/O bandwidth controller and BIO tracking
Hi all,
These are new releases of dm-ioband and blkio-cgroup. The major change
of these releases is that a hierarchical configuration is supported,
a parent cgroup's bandwidth is distributed to its children. The
hierarchical configuration is available when using dm-ioband and
blkio-cgroup together. Please refer to the documentation included in
this series of patches on how to use it.
