In the case of linux/fs.h, I believe that you wanted to remove it
because we are already including linux/fsnotify_backend.h (or
similar), yes? In that case I think it comes down to a similar idea:
keep linux/fs.h when we are directly referencing a function, variable,
etc. that is declared in linux/fs.h. Needless to say, I would take
the same position with other header files.

If you can find a case where we are not making any direct references
to something in a header file, I'm happy to merge a patch which
removes that include.
