This adds support for system-wide logging using four log buffers.
|
|
These are:
|
|
1: main
|
|
2: events
|
|
3: radio
|
|
4: system
|
|
|
|
Log reading and writing is performed via normal Linux reads and
|
|
optimized writes. This optimization avoids logging having too
|
|
much overhead in the system.

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.
