From 1907131bbeabb33db313bad34f3ec1a5faedbd64 Mon Sep 17 00:00:00 2001 From: Jiaying Zhang Date: Mon, 17 May 2010 18:36:03 +0200 Subject: dquot: Detect partial write error to quota file in write_blk() and add printk_ratelimit for quota error messages This patch changes quota_tree.c:write_blk() to detect error caused by partial write to quota file and add a macro to limit control printed quota error messages so we won't fill up dmesg with a corrupted quota file.
