Why? I don't believe these are useful. Because if you actually had use
for them, you would have noticed that you're missing 99% of the reads
issued to the filesystem from the VFS -- through exfat_readahead(),
which you didn't instrument.

So what do you actually want to know, and why can't you get that
information already?
