Hello,
ioctl patch simple route ioctls to underlying block device
-> it supports all ioctl which are supported by your physical device.
e.g.
in simple case you have volume /dev/mapper/VolGroup00-LogVol0
mapped to physical device /dev/sda, inquiry ioctl (using tools from sg3_util)
sg_inq /dev/sda
is the same as
sg_inq /dev/mapper/VolGroup00-LogVol0
In the case of multipath target ioctl command is sent through
active path.
This patch doesn't add some special ioctls to manage dm devices yet.
Milan
