Hello. In releng-4 the device driver's read/write functions check for non-blocking i/o using (flag & IO_NDELAY) Is that changed in current to O_NONBLOCK? As I understand: #include <vnode.h> IO_NDELAY for releng-4 and #include <fcntl.h> O_NONBLOCK for current. Correct? If yes, what exact version should I test for? Thank you, Norbert Koch
