Hi,
Linux 2.6.25 added the MS_I_VERSION flag for inode versioning. Some
text on this should be added to the mount(2) man page. Could someone
of you provide a short description of
* What inode versions are used for
* the MS_I_VERSION flag.
Thanks,
Michael

I don't think it should be documented. It should never have been a
user-visible option to start with and I'm eventually going to fix that.
The correct way to do this would be a feature flag in the superblock.

Agreed, the intention was this was something which NFSv4 would request
of the filesystem, by flipping a bit. I don't see a good reason why a
user would ever want to explicit request 64-bit version numbers, since
they're not even visible to userspace.
