The value was + implemented as a bitshift on a score generated by the badness() + function that did not have any precise units of measure. With the + rewrite, the score is given as a proportion of available memory to the + task allocating pages, so using a bitshift which grows the score + exponentially is, thus, impossible to tune with fine granularity. + + A much more powerful interface, /proc/<pid>/oom_score_adj, was + introduced with the oom killer rewrite that allows users to increase or + decrease the badness() score linearly. This interface will replace + /proc/<pid>/oom_adj. + + A warning will be emitted to the kernel log if an application uses this + deprecated interface. After it is printed once, future warnings will be + suppressed until the kernel is rebooted. diff --git a/Documentation/ABI/testing/sysfs-bus-rbd b/Documentation/ABI/testing/sysfs-bus-rbd new file mode 100644 index 000000000000..90a87e2a572b --- /dev/null +++ b/Documentation/ABI/testing/sysfs-bus-rbd @@ -0,0 +1,83 @@ +What: /sys/bus/rbd/ +Date: November 2010 +Contact: Yehuda Sadeh <yehuda@hq.newdream.net>, + Sage Weil <sage@newdream.net> +Description: + +Being used for adding and removing rbd block devices. + +Usage: <mon ip addr> <options> <pool name> <rbd image name> [snap name] + + $ echo "192.168.0.1 name=admin rbd foo" > /sys/bus/rbd/add + +The snapshot name can be "-" or omitted to map the image read/write.
