All clients connected to the server will be disconnected, they will have to reconnect to the sql server. Affects 4.1 before 4.1.21 and 5.0 (doesn't affect 3.x) The upstream bug is here: http://bugs.mysql.com/bug.php?id=20729
According to upstream this is fixed in 5.0.21, so we should be OK already in FC5 (which is at 5.0.22)
