Patches potentially missing from stable releases

[Henri Rosten <henri.rosten@unikie.com>]

We did some work on analyzing patches potentially missing from stable 
releases based on the Fixes: and Revert references in the commit 
messages. Our script is based on similar idea as described by Guenter 
Roeck in this earlier mail: 
https://lore.kernel.org/stable/20190827171621.GA30360@roeck-us.net/.

Although the list is not comprehensive, we figured it makes sense to 
publish it in case the results are of interest to someone else also.

The below list of potentially missing commits is based on 4.19, but some 
of the commits might also apply to 5.4 and 5.6.

For each potentially missing commit flagged by the script, we read the 
commit message and had a short look at the change. We then added 
comments on our own judgement if it might be stable material or not. No 
comments simply means the potentially missing patch appears stable 
material. "Based on commit" is the mainline patch that has been 
backported to 4.19 and is referenced by the missing commit. We did not 
check if the patch applies without changes, nor did we build or execute 
any tests.
