-/**
- * The ATRACE_TAG macro can be defined before including this header to trace
- * using one of the tags defined below. It must be defined to one of the
- * following ATRACE_TAG_* macros. The trace tag is used to filter tracing in
- * userland to avoid some of the runtime cost of tracing when it is not desired.
- *
- * Defining ATRACE_TAG to be ATRACE_TAG_ALWAYS will result in the tracing always
- * being enabled - this should ONLY be done for debug code, as userland tracing
- * has a performance cost even when the trace is not being recorded. Defining
- * ATRACE_TAG to be ATRACE_TAG_NEVER or leaving ATRACE_TAG undefined will result
- * in the tracing always being disabled.
- *
- * ATRACE_TAG_HAL should be bitwise ORed with the relevant tags for tracing
- * within a hardware module. For example a camera hardware module would set:
- * #define ATRACE_TAG (ATRACE_TAG_CAMERA | ATRACE_TAG_HAL)
- *
- * Keep these in sync with frameworks/base/core/java/android/os/Trace.java.
