Well one thing would be to start with the column and start filling the more 
easy stuff. And if its not known since what kernel version, but its known to 
be stable I suggest to conservatively just put the first kernel version into 
it where people think it is stable or in doubt even put 4.7 into it. It can 
still be reduced to lower kernel versions.

Well: I made a tiny start. I linked "Features by kernel version" more 
prominently on the main page, so it is easier to find and also added the 
following warning just above the table:

"WARNING: The "Version" row states at which version a feature has been merged 
into the mainline kernel. It does not tell anything about at which kernel 
version it is considered mature enough for production use."

Now I wonder: Would adding a "Production ready" column, stating the first 
known to be stable kernel version make sense in this table? What do you think? 
I can add the column and give some first rough, conservative estimations on a 
few features.

What do you think? Is this a good place?

Thanks,
