Default value for the binder.devices parameter.

The binder.devices parameter is a comma-separated list of strings
|

that specifies the names of the binder device nodes that will be
|
|
created. Each binder device has its own context manager, and is
|
|
therefore logically separated from the other devices.

The ashmem subsystem is a new shared memory allocator, similar to
|
|
POSIX SHM but with different behavior and sporting a simpler
|
|
file-based API.
|
|
|
|
It is, in theory, a good memory allocator for low-memory devices,
|
|
because it can discard shared memory units when under memory pressure.
