Comment 18 for bug 666211

Yes: I'm just telling you that the ? entries at the top of these stacks are all "in the scheduler". jbd2 and run-parts are blocked in io_schedule(), and pgbouncer is blocked in do_get_write_access(). Both of those functions are calling into schedule(), and that's what is actually at the top of the stack. (I disassembled the 2.6.35-22.35-virtual kernel and verified the call points from the non-? second entries down on the stack.)
