[PATCH v2 0/2] staging: ion: get one device per heap

From: Benjamin Gaignard
Date: Tue Sep 19 2017 - 06:26:05 EST


version 2:
- simplify ioctl check like propose by Dan
- make sure that we don't register more than ION_DEV_MAX heaps

Instead a getting one common device "/dev/ion" for
all the heaps this patch allow to create one device
entry ("/dev/ionX") per heap.
Getting an entry per heap could allow to set security rules
per heap and global ones for all heaps.

Allocation requests will be only allowed if the mask_id
match with device minor.
Query request could be done on any of the devices.

Benjamin Gaignard (2):
staging: ion: simplify ioctl args checking function
staging: ion: create one device entry per heap
