From bdfc230f33a9dab316dcb6be4696ae59e1562e3c Mon Sep 17 00:00:00 2001 From: Nikitas Angelinas Date: Tue, 18 Oct 2011 10:51:51 -0400 Subject: [PATCH] ext4: MMP: fix error message rate-limiting logic in kmmpd Current logic would print an error message only once, and then 'failed_writes' would stay at 1. Rework the loop to increment 'failed_writes' and print the error message every s_mmp_update_interval * 60 seconds, as intended according to the comment.
