- - Add dt-bindings for remaining heaps (chunk and carveout heaps). This would
10

  - Split /dev/ion up into multiple nodes (e.g. /dev/ion/heap0)

- - The current driver uses the same wait queue for all of the futexes in a
16
-   region. This will cause false wakeups in regions with a large number of
17
-   waiting threads. We should eventually use multiple queues and select the
18
-   queue based on the region.
19
- - Add debugfs support for examining the permissions of regions.
20
- - Remove VSOC_WAIT_FOR_INCOMING_INTERRUPT ioctl. This functionality has been
21
-   superseded by the futex and is there for legacy reasons.
