Not a reason for concern; this was introduced into the kernel to detect (and
then hopefully fix) misbehaving userspace, afaik. Having these messages in the
debug ringbuffer is annyoing for sure, but seeing it make its way into your
syslog is what really drove me a bit mad (esp. as Proxmox seems to poll block
devices in a weird way, which generated such messages at a rate of several
dozen entries per minute...).

I made rsyslog (on Debian Squeeze) discard the kind of message by introducing
a regex filter to its chain of rules by creating a file
"/etc/rsyslog.d/zz-local.conf" with the following lines as its content:

:msg, regex, ".*sending ioctl [0-9][0-9]* to a partition.*" ~
:msg, regex, ".*scsi_verify_blk_ioctl: [0-9][0-9]* callbacks suppressed.*" ~

Maybe that's helpful for someone who doesn't like getting their logs spammed
with pretty meaningless noise, too.
