relatime is default
logbufs=8 is default
attr2 is default
barrier is default
largeio is not likely anything you want or need
swalloc is unlikely to be useful on a laptop
People need to read up a little and know what they're tuning;
repeating this kind of suggestion leads to cargo-cultism for
performance "tuning"
IOW don't turn knobs just because they are there ... :)
