As a prerelease kernel, we have never relied on <N> for ordering, nor should we. This is not a valid 5.12 release. 5.12.0-1 should supercede it. I will say that the release bump is not entirely necessary, though you can get into the case of building multiple snapshots in the same day (rarely), and it can matter. I thought the solution we agreed upon was to reset the release number for each kernel series, so when we start snapshots for 5.13, that 186 drops back to 1.
