The "official" size limit is 10x16x24, but you'll be fine. You are close enough to the standard that no one will notice. Besides, I've never seen the airline size check a carry on, and you would not believe the "whale" sized items that people bring on board - far, far bigger than 22x10x19.
Make sure that you get on the plane early enough that there is remaining overhead storage.
The last few flights I have taken have been full and the late boarders had to gate check items.
