Re: backport "x86: change default to spec_store_bypass_disable=prctl spectre_v2_user=prctl"

Why is this required at all? It just changes a default option, you can set the "faster" option yourself if you really feel it is a good idea for older kernels, why can't you do that for containers you want it enabled on for these older kernels?

The patch has already motivations of why this is a better default, and changing this would give performance improvements

And what exact kernel versions did you test this on?

this was tested on 5.15 and 5.10

And how is this not a new feature?

As you mentioned it changes the default option, Why is this considered a new feature?
