[PATCH OLK-6.6] blk-ioinf: fix default weight being reset to 0 for non-root cgroups
by Baokun Li 19 Nov '25

19 Nov '25

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/ID0C1D -------------------------------- The legacy blkio cgroup treats both `/sys/fs/cgroup/blkio` (the true root) and `/sys/fs/cgroup/blkio/1` (often the first user-created cgroup) as root when initializing the per-device (pd) structure. Consequently, if a default weight is set for the non-root cgroup (`/sys/fs/cgroup/blkio/1`), it is incorrectly overwritten and reset to 0 inside `ioinf_pd_init()`. This patch resolves the issue by increasing the priority of the `IOINFG_WEIGHT_UNINIT` check, ensuring that an explicitly set default weight is honored and is not reset when the `pd` is initialized.

[PATCH OLK-6.6] arm64/mpam: Add build dependencies for CONFIG_RESCTRL_IOMMU
