[dm-devel] [PATCH] dm: move device check warning messages into debug level

[Milan Broz]

The device-mapper should not send warning messages to syslog
if device is not found. This should be done in userspace
according to returned dm-ioctl error code.

Move these messages into debug level and use rate limiting
to not flood syslog.
