When we last discussed pullups for 1.4.12, we decided that these were too high 
risk for that release (the changes appeared very late in the release cycle). 
MS_NOATIME is sufficiently large that it doesn't appear to conflict with any 
inode flags, up to and including Linus's current kernel, so there doesn't 
appear to be a risk associated with not taking them this time round.

I'd hope that the MS_NOATIME -> S_NOATIME change will land on the 1.4 branch 
immediately after we release 1.4.12, and thus be in 1.4.13. The change to the 
super block flags requires more thought, as the impact is potentially far 
reaching. I'd like to see significantly more testing of that change before we 
commit to it in a stable release.

If you've got any information that challenges this - please let us know. In 
particular, if you can point us at any shipping kernel where the MS_NOATIME bit 
is used as an inode flag, that would be very helpful. It's looking like there 
will be at lease one more release candidate before 1.4.12 is finalised.

Cheers,

Simon.
