The following devices parameters are defined:
devices.allow
Specifies a device that a cgroup is allowed to access by its
type (a for any, b for
block, or c for character), its major and
minor numbers, and its access modes (m for
create permission, r for read access, and
w for write access).
For example, b 8:17 rw would allow read and
write access to the block device /dev/sdb1.
You can use the wildcard * to represent any
major or minor number. For example, b 8:* rw
would allow read and write access to any
/dev/sd* block device.
Each device that you specify is added to the list of allowed devices.
devices.deny
Specifies a device that a cgroup is not allowed to access.
Removes each device that you specify from the list of allowed devices.
devices.list
Reports those devices for which access control is set. If no
devices are controlled, all devices are reported as being
available in all access modes: a *:* rwm.
