Which ioctl with more than 16kB

Unanswered. Let's ask the same question in a different way:
Please supply the output of these three commands on the real-world system on
which you believe that that particular allocation is causing you a problem:
dmsetup info -c
dmsetup table
dmsetup status
Android doesn't include the command. We compiled lvm2-2_02_107.tar.gz and copy
dmsetup to the board. But command reports No devices.
# /data/bin/dmsetup info
No devices found
# cat /proc/devices
