Comment (by korli):
Coldfirex, please see https://git.haiku-os.org/haiku/tree/src/add-
ons/kernel/drivers/disk/usb/usb_disk/usb_disk.cpp#n1802
basically it should be like: https://git.haiku-os.org/haiku/tree/src/add-
ons/kernel/generic/scsi_periph/io.cpp#n406
{{{
if (IS_USER_ADDRESS(buffer)) {
if (user_memcpy(buffer, &ready,
sizeof(status_t)) != B_OK)
return B_BAD_ADDRESS;
} else if (is_called_via_syscall()) {
return B_BAD_ADDRESS;
} else
*(status_t *)buffer = ready;
}}}
