preventing atime updates for cache files isn't currently effective.
The split between MS_NOATIME (as a super block flag) and S_NOATIME (as
an inode flag) seems to have happened with 2.4.0.
I've put a patch to address this into gerrit as
http://gerrit.openafs.org/1070
Also, given AFS itself doesn't appear to track access times, shouldn't
src/afs/LINUX*/osi_vfsops.c (again, all versions) set MS_NOATIME in its
super block?
Yes, I think it probably should. A patch for this is in gerrit as
http://gerrit.openafs.org/1071
I suspect this one will require a lot of testing, just to make sure the
mount options change has no unintended side effects.
