SubjectBIG files & file systems
Hi, 

I've just been told that some "limitations" of the following kind will
remain:
page index = unsigned long
ino_t = unsigned long

Lustre has definitely been asked to support much larger files than
16TB. Also file systems with a trillion files have been requested by
one of our supporters (you don't want to know who, besides I've no
idea how many bits go in a trillion, but it's more than 32).

I understand why people don't want to sprinkle the kernel with u64's,
and arguably we can wait a year or two and use 64 bit architectures,
so I'm probably not going to kick up a fuss about it.

However, I thought I'd let you know that there are organizations that
_really_ want to have such big files and file systems and get quite
dismayed about "small integers". And we will fail to deliver on a
requirement to write a 50TB file because of this.

My first Linux machine was a 25MHz i386 with a 40MB disk....
