schdule() doubt

["nidhi mittal" <nidhimittal19@xxxxxxxxx>]

actually i saw that ..
set_current_state (TASK_INTERRUPTIBLE)
schedule()

as far as i understood
these two are independent statements 

where in first statement we just change the state variable in proces descriptor 
and in 2nd statement we put process to actual sleep 

now my ques is 
if process is interrupted between these two statements by any means......
wont it be in some corrupt state
where its not sleeping but running but its state is changed to TASK_INTERRUPTIBLE...............


pl clarify why didnt we make these statements as one atomic statement ....
