- * percpu partition lock

- * There are some use-cases like this in Lustre:
- * . each CPU partition has it's own private data which is frequently changed,

- * . all CPU partitions share some global data, these data are rarely changed.
- *
- * LNet is typical example.
- * CPU partition lock is designed for this kind of use-cases:
- * . each CPU partition has it's own private lock
- * . change on private data just needs to take the private lock
- * . read on shared data just needs to take _any_ of private locks
- * . change on shared data needs to take _all_ private locks,
- *   which is slow and should be really rare.
