Hi all, This is a new release of blkio-cgroup v11. Changes: - The function cgroup_get_from_page() is added which determines to which cgroup a given page belongs. This function is introduced from Vivek's io-controller patch. Thanks Vivek. - Fix a type mismatch of the refcount of io_context. The refcount has been changed to atomic_long_t. This patch can be applied to 2.6.31-rc7. The

Hi everyone, This is a new release of dm-ioband and bio-cgroup. With this release, the overhead of bio-cgroup is significantly reduced and the accuracy of block I/O tracking is much improved. These patches are for 2.6.28-rc2-mm1. Enjoy it! dm-ioband ========= Dm-ioband is an I/O bandwidth controller implemented as a device-mapper driver, which gives specified bandwidth to each job running on
