--- Comment #6 from Ahmad Khalifa <[email protected]> --- The priv->mtx lock is given to kqueue through knlist_init_mtx (which is called in gpioc_open). It gets locked by knlist_mtx_lock (which is a generic implementation, since we never give one to kqueue) before it calls the knote's f_event (which in our case is gpioc_kqread). As for the ioctl race, yes, that does look like an oversight. I will try to get that fixed ASAP. Thank you for the report. :) -- You are receiving this mail because: You are the assignee for the bug.
