CopyFail only highlights why Companies want LTS. If there was a supported kernel built prior to 2017, most large companies would still be on that version, avoiding this issue all-together.
The corporate mindset is usually "never upgrade unless there is new hardware needed or critical software failure". All CopyFail did was reinforce that mindset.
I wonder if CopyFail will cause enterprises put pressure on the Linux Foundation to maintain a "ultra LTS" were it is supported for 20 years ?
