Kernel 6.2.x.x compilation complains

[maestrosoft]

With kernel 6.2.x.x the file system API has been redefined with new members. Can you update the source code with the new API?

It appears that this repository has not been maintained for years. You might want to consider trying simplefs as an alternative. The latter supports Linux 6.x kernels.

Hi @guy, thanks for the report!

I've opened PR #4 to address these compilation errors for Kernel 6.2.x.x. This update adjusts the function signatures for create and mkdir, and handles the removal of readdir to match the new API.

Let me know if this resolves the issue for you!
