[PATCH] lsm: add task_setioprio hook
Implement an LSM hook for setting a task's IO priority, similar to the hook
for setting a tasks's nice value.
A previous version of this LSM hook was included in an older version of
multiadm by Jan Engelhardt, although I don't recall it being submitted
upstream.
Also included is the corresponding SELinux hook, which re-uses the setsched
permission in the proccess class.
