Cloning this bug to add the relatime patch back to Fedora 11.

Thanks & regards, Phil

Hi Phil,

I think we were expecting an alternate version of this patch to have gone upstream by now... I'll review the alternate patch, versus mingo's original patch and we'll see.

regards, Kyle

Merged upstream, and backported to Fedora 10, Fedora 11 and Rawhide:
https://www.redhat.com/archives/fedora-devel-list/2009-March/msg01612.html

Fedora 11 will have relatime as default, Fedora 10 won't have it as default,
but will support it.

Awesome, thanks a lot Ricardo & Matthew!

Closing this bug as fixed in rawhide then.
