Hi, Can anybody explain the example? I am confused by the `{-.-...}`. 43 44 When locking rules are violated, these state bits are presented in the 45 locking error messages, inside curlies. A contrived example: 46 47 modprobe/2287 is trying to acquire lock: 48 (&sio_locks[i].lock){-.-...}, at: [<c02867fd>] mutex_lock+0x21/0x24 49 50 but task is already holding lock: 51 (&sio_locks[i].lock){-.-...}, at: [<c02867fd>] mutex_lock+0x21/0x24 52 53 54 The bit position indicates STATE, STATE-read, for each of the states listed 55 above, and the character displayed in each indicates: 56 57 '.' acquired while irqs disabled and not in irq context 58 '-' acquired in irq context 59 '+' acquired with irqs enabled 60 '?' acquired in irq context with irqs enabled.
