- - Remove ION_IOC_CUSTOM: Atm used for cache flushing for cpu access in some
- vendor trees. Should be replaced with an ioctl on the dma-buf to expose the
- begin/end_cpu_access hooks to userspace.
- Clarify the tricks ion plays with explicitly managing coherency behind the
dma api's back (this is absolutely needed for high-perf gpu drivers): Add an
explicit coherency management mode to flush_for_device to be used by drivers
