    SubjectRE: [PATCH 3/3] EDAC: Convert AMD EDAC pieces to use RAS printk buffer

    This looks unpleasant if your userspace agent set this sysfs file, and
    then dies (or gets killed).

    Perhaps you need some device file that the agent keeps open (so if the
    agent goes away, the kernel gets a "close" on the device to tell it
    to revert). But even with this sort of solution you would still have
    to worry about races.
