I noticed that most functions in libfs.c are called "simple_*" when they
do the right thing for the majority of simple use cases (e.g.,
simple_symlink_inode_operations or simple_dir_operations). I can
certainly rename the function.
Thank you for all the feedback, I will incorporate it and send a new
patch series soon.
