Procedure; Human Factors
I was cleared by Tower to depart Runway XX runway heading. As I rolled onto the runway I noticed an aircraft on final and I told Tower I would expedite. At this time they told me to hold short; I was already on the runway and rolling for departure and I relayed this to Tower. I heard them tell a regional jet to go-around and canceled landing clearance. I was already airborne; 75-100 feet on runway heading when they came back to me and told me to continue ground roll and exit the runway when able. I again relayed that I was already airborne and could not comply.I watched on G1000 ADS-B as the regional jet approached me from behind and left. I remained at a low altitude and watched them visually as it passed me high and to the left. Once it was well clear I continued my climb and was handed off to Departure. From there I was given on course and continued the short flight. I was the sole occupant of the aircraft. I use this airport frequently and have been instructed to depart with varied aircraft on final on many occasions.
