From 7cb6579572b50ef44bc0a321a4c73cce55b0c2f2 Mon Sep 17 00:00:00 2001 From: Chen Qi Date: Fri, 1 Mar 2019 15:22:15 +0800 Subject: [PATCH] do not disable buffer in writing files Do not disable buffer in writing files, otherwise we get failure at boot for musl like below. [!!!!!!] Failed to allocate manager object. And there will be other failures, critical or not critical. This is specific to musl.
