Re: [RFC] Improved inode number allocation for HTree

[Hans Reiser]

Let's make noatime the default for VFS.

So what?  It still tells you where to restart.  Strictly speaking, you 
would want to allow the filesystem to choose what it wants to return to 
indicate position.  For htree and reiserfs this would be a filename or 
its hash, for ext2 without htree this would be a byte offset.

We are designing Linux.  You know, Microsoft and Steve Jobs continue to 
design.  We should too.

Needless change should be avoided.  Failure to change when something is 
known to be broken leads to being inferior to those who do change.

Let's design something that does it right.  Or else SCO will be right in 
saying that Linux is just a Unix ripoff by people who couldn't do 
anything unless Unix had been written to tell them how to do it right.
