I have written a custom device driver as an out of tree kernel module. This device driver defines a set of ioctls that are needed by user space applications. The ioctls are defined in a custom header file.
What is the standard location where this header file should be installed? Should this be /usr/include? Or perhaps the same location where the standard kernel include files are installed?
I have read this question but it does not specify where the custom header files should be installed.
