Moxa HDD/SSD hot swap driver

The hotswap driver is for moxa V2616A embedded computer. /dev/hotswap is the entry point for tracking the disks hotswapping. You can use the 'mxhtspd' to monitor and programming the button and harddisk hotswap. The mxhtspd provides a callback script for stopping your program and hotswapping your disk in run time. Following describes how to compile this driver.

Setting the path to your kernel source tree in Makefile

To compile this driver, you should modify the KDIR to the path of your kernel headers. We configure the KDIR in Makefile for configuring the path of the kernel headers.

# to install Linux headers
$ apt update && apt install linux-headers-`uname -r`

KDIR=/lib/modules/`uname -r`/build

Compile & install the driver
