Re: [PATCH v3 3/4] mm: prevent KSM from breaking VMA merging for new VMAs

[Lorenzo Stoakes]

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
