Yes, in all the refactoring/rebasing, somehow the line which should have removed 'flags' there ended up in https://lore.kernel.org/all/[email protected]/ along with another one-liner that should have been in a different previous commit and breaks bisectability of that too. Sorry about that. Should all be fixed in https://git.infradead.org/?p=users/dwmw2/linux.git;a=shortlog;h=refs/heads/kvmclock5 where I'm accumulating various fixes in preparation to post a v5.
