Comment 5 Luboš Luňák 2021-11-29 12:58:57 UTC
As the commit message says, that commit basically reverts a previous commit. So whatever the problem is, it most likely was present even before that previous commit, so this is in fact not bisected (unless you're certain that the problem really was introduced by that commit and not just by it being a revert).
