questions on wait_event ...

["Alexey Shinkin" <alexshinkin@hotmail.com>]

Hi , all !
Could anyone please clarify one thing in that old well known
wait_event_... code (taken from 2.6.5 wait.h ):

#define __wait_event_interruptible(wq, condition, ret)          \
do {                                                                    \
       wait_queue_t __wait;                                     \
       init_waitqueue_entry(&__wait, current);           \
                                                                       \
       add_wait_queue(&wq, &__wait);                   \
       for (;;) {                                                      \
               set_current_state(TASK_INTERRUPTIBLE);    \
               if (condition)                                          \
                       break;
........................................

Is it possible that scheduling happen after set_current_state() but before
checking the condition ?
If yes - even if we will have condition==TRUE by this moment - the scheduler
will make the process to sleep anyway , right ?
