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....
