I cannot even parse this comment.
Does "When a freshly created task is scheduled once, changes its state to TASK_UNINTERRUPTIBLE" mean "When a freshly created task is scheduled once and it changes its state to TASK_UNINTERRUPTIBLE"?
Does this "it must not be checked" read as "it shall not be checked" (as in "because if you check it, something goes wrong") or "it is not required to be checked" (as in "usually, you need to check it (otherwise something goes wrong), but here in this case, you do not need to check it, because it cannot go wrong in this case")?
Fixing spelling mistakes is okay, but it is even better to check the sentence you are correcting and try to comprehend it.
