Sashiko comment (https://sashiko.dev/#/patchset/20260319052157.99433-4-sj@kernel.org) below. : This isn't a bug, but the phrasing "does nothing but only online parameters : updates" is a bit awkward. Could this be reworded for clarity, perhaps to : something like "does nothing other than apply online parameter updates"? I pretty sure Sashiko is more English fluent than I. But, shouldn't 's/apply/applying/' ? I will update the sentence to "When it is paused, the kdamond does nothing other than applying online parameter update" in the next revision. Thanks, SJ [...]
