I would like to get some help to write a kernel extension called filzip
when the filzip is loaded into the kernel (load filzip with parameter <filename>)
it creates a special file /dev/fzip_<filename> that implements all file operations (open, read,write,...)
and the kernel extension filzip manages a compressed version of the original file.
How can I implement this? since I never wrote a kernel extension I need a sample code (a template) that
I can use to fill the rest of the code.
PS: I am not sure, but for now I do not want to use a file system that save compressed data on physical disk;
I really want a kernel extension that manages a compressed copy of an existing file.
Thank you for your help
