From 810b492375f4aed5ce222982054adc0394a4bd33 Mon Sep 17 00:00:00 2001 From: Milan Broz Date: Thu, 13 Jan 2011 19:59:55 +0000 Subject: [PATCH] dm ioctl: suppress needless warning messages The device-mapper should not send warning messages to syslog if a device is not found. This can be done by userspace according to the returned dm-ioctl error code. So move these messages to debug level and use rate limiting to not flood syslog.
