create sysfs class attribute and sub directories

[Jeshwanth Kumar N K <jeshkumar555@xxxxxxxxx>]

Hello List :),

I have a small question about sysfs.

I am creating a kernel module to print some versions in sysfs attributes. So the directory tree would be.

/sys/class/versions/main/version

                          /dev/version

So, versions is my class directory, inside that two directories main and dev, both directory should contains version attribute. I am little familiar with creating with sysfs class attribute using struct class, but how to create the directory (like main/dev) and create attributes in both directory ?

I have one more question, Is sysfs is right place to display version information ? 

Thanks in Advance :)
