From 39a0e975c37dee93fa1b8ea5f7eacd1c4c8a586e Mon Sep 17 00:00:00 2001 From: Jungseung Lee Date: Mon, 12 Dec 2016 16:46:43 -0800 Subject: [PATCH] init: reduce rootwait polling interval time to 5ms For several devices, the rootwait time is sensitive because it directly affects booting time. The polling interval of rootwait is currently 100ms. To save unnessesary waiting time, reduce the polling interval to 5 ms.
