The fdc worker thread was using a one second timeout while waiting for a new bio to arrive or for the device to detach. However, the driver already does a wakeup when queueing a new bio or asking the thread to detach, so the timeout only served to waste CPU time waking up the thread once a second just so it could go right back to sleep. Use an infinite timeout instead. Discussed with: phk Sponsored by: Netflix |
