Hi Andrew, Sending a fix-patch for this commit due to a reported syzbot issue which highlighted a bug in the implementation. I discuss the syzbot report at [0]. [0]: https://lore.kernel.org/all/a55beb72-4288-4356-9642-76ab35a2a07c@lucifer.local/ There's a very minor conflict around the map->vm_flags vs. map->flags change, easily resolvable, but if you need a respin let me know. I ran through all mm self tests included the newly introduced one in 4/4 and all good. Thanks, Lorenzo ----8<----
