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

A migrating transparent huge page has to already be unmapped. Otherwise, the page could be modified while it is being copied to a new page and data could be lost. The function __split_huge_pmd() checks for a PMD migration entry before calling __split_huge_pmd_locked() leading one to think that __split_huge_pmd_locked() can handle splitting a migrating PMD. However, the code always increments the

Hi all, With this series of patches, you can determine the owners of any type of I/Os. I ported the previous version to linux-2.6.26-rc2-mm1. This makes dm-ioband -- I/O bandwidth controller -- be able to control the Block I/O bandwidths even when it accepts delayed write requests. Dm-ioband can find the owner cgroup of each request. It is also possible that OpenVz team and NEC Uchida-san team
