Regarding the kernel version detection, this was certainly considered
but there doesn't seem to be any simple way to do it. However, now that
you mention it, this can certainly be an inconvenient issue with
incoming connections for devices which we've never seen during a device
discovery. Therefore, some kind of a userspace workaround for this would
imho be desirable and I'd certainly be willing to accept a patch for it
as long as it doesn't get too complicated. I suppose it's sufficient if
the patch would be for hciops only since any system running mgmtops
would also have a kernel that does the name request.
