The shims MPRIO_RAID_ACTION32 maps to native MPRIO_RAID_ACTION which the native ioctl switch does not implement (falls to ENOIOCTL) \u2014 the RAID-action ioctl surface (mpr_ioctl.h:101-114,362) is dead. Pass-2 checklist item (d) answered: no RAID-action buffer-sizing bug exists because no handler exists.",
