My current instance is attempting to modify the max number of loop devices.
One pellet of Google buckshot reminded me that it can be reset for the next
re-boot under /etc/modprobe.d . But I want to reset it on the fly.
Other pellets hit postings:

If you have loop compiled in to the kernel, as I do below, you can
only change the number of loop devices at boot by using
"max_loop=<number_of_loop_devices" on the kernel cmdline.
# grep BLK_DEV_LOOP /boot/config-3.15-rc5
CONFIG_BLK_DEV_LOOP=y
CONFIG_BLK_DEV_LOOP_MIN_COUNT=16
But if the above grep returns "CONFIG_BLK_DEV_LOOP=m", you can:
# rmmod loop
# modprobe loop max_loop=<number_loop_devices_minus_one>
