This patch converts ioctl call to unlocked_ioctl form. It's possible due to rtl_lock spinlock protection. Signed-off-by: Cyrill Gorcunov --- The patch is *not* tested but the patch does not bring _much_ changes so it wouldn't break the compilation procedure. If there is problem with attachment - i could send it as inline form today evening. Andi, Jiri, Alexey the only thing I do complain about - is time set/read from several user threads that uses same (duplicated) file descriptor. Could there be useless thread spins instead of sleep (in case if this unlocked_ioctl were protected by mutex)?
