Remember, the files don't have an ei allocated. Only directories.

Crossed emails.

I then counted the length of the string - 7 bytes (which is the same as the
length of the string plus the '\0' character - 8 bytes) to accommodate the
pointer size, and it's a savings of 22KB per instance. And in actuality, I
should have rounded to the nearest kmalloc slab size as kzalloc() isn't going to
return 35 bytes back but 64 bytes will be allocated.

No. See my other email. The kmalloc sizes actually means that it comes
out exactly even.
