I seem to be hitting some very weird corner case causing an assertion failure. The offender is ZFS Event Daemon:
The following code shows the offence:
struct udev_device *dev;
if ((dev = udev_monitor_receive_device(mon)) == NULL) {
zed_log_msg(LOG_WARNING, "zed_udev_monitor: receive "
"device error %d", errno);
continue;
}
…..
sectors = udev_device_get_property_value(dev,
"ID_PART_ENTRY_SIZE");
if (sectors == NULL)
sectors = udev_device_get_sysattr_value(dev, "size");
Im at a loss here as to what’s causing the assertion failure. Both udev_device_get_property_value and udev_device_get_sysattr_value only assert a valid udev_device pointer. How can the pointer get lost between these two function calls?

you need to poll before any valid udev_device is returned to you.
