As the article states, BQL has been around since 2011 so it's most likely available - you can grep for CONFIG_BQL in your /boot/config-* file to confirm.

I'm not aware of any up-to-date list of drivers that support BQL. You could try something like [1], but I'm not sure if it will find all relevant drivers.
