Hi Andrew,
Please add the following patch to the queue for the next merge window.
It fixes a longstanding issue of fdatasync() implementation of NILFS2
where fdatasync() will fall back to a full sync most of the time. The
fallback is only necessary for a change of the file size and not for a
change of the various timestamps. Andreas Rohner fixed this issue by
discerning these situations properly.
Thanks,
Ryusuke Konishi
