The required serialization of NOSY_IOC_START and NOSY_IOC_STOP is already provided by the client_list_lock. NOSY_IOC_FILTER does not really require serialization since accesses to tcode_mask are atomic on any sane CPU architecture. Nevertheless, make it explicit that we want this to be atomic by means of client_list_lock (which also surrounds the other tcode_mask access in the IRQ handler). While we are at it, change the type of tcode_mask to u32 for consistency with the user API. NOSY_IOC_GET_STATS does not require serialization against itself. But there is a bug here regarding concurrent updates of the two counters by the IRQ handler. Fix it by taking the client_list_lock in this ioctl too.
