| ---help--- |
| 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. |

| bool "Android Low Memory Killer" |
| ---help--- |
| Registers processes to be killed when low memory conditions, this is useful |
| as there is no particular swap space on android. |
| |
| The registered process will kill according to the priorities in android init |
| scripts (/init.rc), and it defines priority values with minimum free memory size |
| for each priority. |

| ---help--- |
| A sync object driver that uses a 32bit counter to coordinate |
| synchronization. Useful when there is no hardware primitive backing |
| the synchronization. |
| |
| WARNING: improper use of this can result in deadlocking kernel |
| drivers from userspace. Intended for test and debug only. |
