This is wrong. If you really want the dentry count (which I doubt, I
don't see why this code would care _even_ just for a debug printout),
you should use
d_count(aio_ring_file->f_dentry)
instead these days. That will get the count from the right place,
regardless of any lockref issues or anything else (and f_dentry may be
the "old" way to get the dentry, but it's still supported and unlikely
to go away. No point in writing out "f_path.dentry" unless you *want*
to be aware of the fact that f_path has both a dentry and a mnt member
- but most people really don't care about the mnt information).
