In most filesystens atime updates aren't transactional.  They just
get written into inode->i_atime, and at some later point when the
VFS tries to clean the inode it gets writtent back, either through
a transaction or not.

Yes, agreed. But then when a F.S is frozen the inode should not be dirtied? Right? So this has to be fixed?
Also, in ext4, I think that updating atime starts a transaction.
