Robert Love	11980c2	2011-12-20 16:49:48 -0800	[diff] [blame]	10	The ashmem subsystem is a new shared memory allocator, similar to
				11	POSIX SHM but with different behavior and sporting a simpler
				12	file-based API.
				13
Cruz Julian Bishop	d7f9729	2012-12-22 09:00:46 +1000	[diff] [blame]	14	It is, in theory, a good memory allocator for low-memory devices,
				15	because it can discard shared memory units when under memory pressure.

				21	This adds support for system-wide logging using four log buffers.
				22
				23	These are:
				24
				25	1: main
				26	2: events
				27	3: radio
				28	4: system
				29
				30	Log reading and writing is performed via normal Linux reads and
				31	optimized writes. This optimization avoids logging having too
				32	much overhead in the system.
