Perhaps I dont understand you wrongly, but from what your sayings, the meaning came out is that: I dont care race so whether or not interruptible_sleep_on or wait_event_interruptible be used isnt important for me. interruptible_sleep_on is depreceated so you should stick to wait_event_interruptible in any case. > thanks, > > Chris. -- Bora SAHIN -- Kernelnewbies: Help each other learn about the Linux kernel.
