 * This file describes the project ID values we use for filesystem quota

 * tracking.  It is used on devices that don't have the sdcardfs kernel module,

 * which requires us to use filesystem project IDs for efficient quota

 * calculation.

 * These values are typically set on files and directories using extended

 * attributes; see vold for examples.
