From adb9743d6a08778b78d62d16b4230346d3508986 Mon Sep 17 00:00:00 2001 From: Qi Zheng Date: Sun, 25 Jun 2023 15:49:37 +0000 Subject: binder: fix memory leak in binder_init() In binder_init(), the destruction of binder_alloc_shrinker_init() is not performed in the wrong path, which will cause memory leaks. So this commit introduces binder_alloc_shrinker_exit() and calls it in the wrong path to fix that.
