Subject: [PATCH v2 0/2] Binder: Add timestamp and async from to transaction record

From: Chuang Zhang <zhangchuang3@...omi.com>

This path adds support for getting the pid, tid, and transfer duration
information of transfers in binderfs transfer records.
Previously, this information was not available in the transfer records,
which made it difficult to analyze certain issues in Android.

With this modification, Android engineers will be able to quickly identify
and diagnose problems in certain scenarios. We believe that this
improvement will be particularly useful for issue analysis and debugging
on Android.

This change does not affect existing functionality or performance and
is fully backward-compatible.
