I am working on writing a file system for the linux 2.2.14-6.1.1 kernel. I have a few questions: 1) should the file system that works on 2.2.14-6.1.1 work on 2.4.X kernels? 2) what is required to simply mount the file system? i have the module compiling and it is showing up in the /proc/filesystems, but when i try a mount (i just wanna mount it - babysteps) i get a seg fault. Then when i do a rmmod it says "Device or resource busy". I have what i think is a fully working read_super function but do more functions need to be implemented? (I am not attatching the source since its more then 10 lines, if you want a copy to better help then ill gladly send it.) Thank you in advance!
