Do constant spell-like abilities still function while the affected creature is unconscious?

[SirCasimir]

My character has constant feather fall and was knocked unconscious while falling; does she plummet to her death or float safely to the ground?

[Meirril]

Feather fall doesn't require any decisions. So long as it has duration remaining creatures affected fall at 60' per round and if they land take no damage.

Now if you had fly cast on you and went unconscious then you'd fall like a normal flying creature would. Though if the duration of fly ran out or if it was dispelled you'd be treated as if you were under the effects of Feather Fall for 1 round like the Fly spell says.
