I was wondering how we can overwrite the copy functionality while writing our own filesystem in linux. VFS does not offer any sort of API for copy. I think it calls create and write when we execute the copy the file/dir.
Which you can verify using strace. Which you should already be familiar with if you have the experience needed to write a usable filesystem.
I am interested in overwriting the way copy happens in my filesystem(which I am writing for fun :p).
And what, exactly, do you want copy to do differently on the API level, and on the file system level?
