Hi,
I happened to come across this discussion. I am having a similar issue. I am using Rhel7-3.10.0-123 kernel. I tried all the options that are mentioned above and none of
the api's
including kern_path() return valid dentry value. My requirement is to fetch directory name from filepath.
Why do you need a directory name from a filepath within the kernel? What problem are you trying to solve that you feel a directory name is the correct solution?
And remember, namespaces, what does a "directory name" really mean... :)
thanks,
greg k-h

Hi Priya, Please make use of a single thread for one topic. There was another thread by you on the same topic. Anyways, I am replying to this one. Greg has asked questions that you should ask yourself before going on with choosing one approach. I had suggested you using kern_path() earlier, since it doesn't makes use of nameidata, but as you are telling its not working too. Here I would like to know the actual context of the approach so as to figure out if something I know that can work for you or maybe you shouldn't be doing it that way. Enjoy life, Rohan
