I guessed, it can be no-go, this is why I wrote that this feature isn't required for iSCSI-SCST functionality. But, since the implementation is *so* simple and doesn't do any layering violation, I have a hope that once it disabled by default it will be harmless and, hence, could be accepted. Only few people need this feature. Otherwise there will be an alternative for them between enable that feature, then recompile, vs patch the kernel, enable that feature, then recompile.

When I was developing it my main goal was to do it as simple as possible. I believe, I succeeded in it. If it's rejected, it will simply live out of tree until me or somebody else finds time to reimplement it in an acceptable, although at least 10 times more complicated manner.

Thanks, I'll follow your advise.
