SubjectRe: [patch] smarter atime updates

yes, that'd be fine. The more conventional approach
would be to blow away the strange UPPER CASE name and:

static inline void update_atime(struct inode *inode)
{
if (inode->i_atime != CURRENT_TIME)
__update_atime(inode);
}

But that would be a bigger patch, and I rather like shaving
off three quarters of the sys_read() overhead with a two-liner ;)
