Hello! > Yes. On 2.4 (at least) there is nothing to prevent the driver's ioctl() > function from running on two or more CPUs simultaneously. I apologize, the reply is late a bit. However, I have to remind that open/close/ioctl __are__ serialized with global semaphore. To Andi: BKL is fully useless here, just because these calls are allowed to sleep. The problem does not exist. Alexey |
