As Mr. Hansteen said, softdep was removed versions ago.

Noatime only matters when the CPU outruns the mass storage long enough
for memory to fill with dirty inodes.
Then the system seems to pause while they are pushed out to storage.
Using a SSD and the large RAM in modern systems that rarely happens.

Using rotating rust and (relatively) little RAM doing a grep through
many thousands of small files it's not too hard to cause the situation.

Softdep could fill RAM with dirty inodes pretty easily.
