Package: mdadm
Version: 3.2.3-2
Severity: normal

Dear Maintainer,

After upgrading my system to the latest sid packages I'm seeing the following errors
in the kernel log:

[    4.334881] mdadm: sending ioctl 800c0910 to a partition!

[  368.892442] mdadm: sending ioctl 1261 to a partition!

The upgrade included updates for mdadm and the linux kernel.

The updates installed linux kernel 3.2, which I assume is triggering this.
Recently there was a security issue with ioctls sent to partitions being
forwarded to the whole disk. I assume the 3.2 kernel has a fix for this and
this is causing the messages.

So far the systems seems to work correctly.

Regards,

Rik
