From fd66950d547fd000a7ad651972ced3429835bc3a Mon Sep 17 00:00:00 2001 From: Carlos Llamas Date: Thu, 26 Sep 2024 23:36:19 +0000 Subject: [PATCH] BACKPORT: FROMGIT: binder: add delivered_freeze to debugfs output Add the pending proc->delivered_freeze work to the debugfs output. This information was omitted in the original implementation of the freeze notification and can be valuable for debugging issues.
