sf buf allocation, use wakeup() instead of wakeup_one() to notify sf buffer waiters about free buffer. sf_buf_alloc() calls msleep(PCATCH) when SFB_CATCH flag was given, and for simultaneous wakeup and signal delivery, msleep() returns EINTR/ERESTART despite the thread was selected for wakeup_one(). As result, we loose a wakeup, and some other waiter will not be woken up. Reported and tested by: az Reviewed by: alc, jhb MFC after: 1 week |
