Jens,

Actually we might work to issue a patch and revert the patch plus add the code
that Bean and Bart mentioned which is currently Android only.
The reason it has not been done before is because for now it's not production yet
but it may soon be that case.

Would this patch revert be an option and accepted as a closure for this discussion?

Another option (which I actually prefer), if I ask for a MM & Storage BoF discussion
on storage hints where I can show you the status of temperature management
and my studies on how this is beneficial for storage devices.

Would this be more beneficial and maybe get some wider consensus
on the write hints?

After that consensus reverting (or agreeing on a new approach) will be easier.
