Gaah. I just merged Andrew's MM tree, and while it had a lot of small conflicts (and the ext4 ones were annoying semantic ones), the only one that was in *confusing* code was the one introduced by this one-liner fix.
I'm pretty sure I did the right thing, particularly given your other patch for the mm tree, but please humor me and take a look at it?
Sure, took a look and looks correct to me, thanks!
That 'vma_merge()' function is the function from hell.
Yeah, unfortunately. But despite the bugs, I believe Liam's changes in 6.3 improved it a lot, as with __vma_adjust() it was much worse (it did e.g. things like "swap(vma, expand)" in some cases). And hopefully the cleanups from me and Lorenzo in the mm 6.4 pull request improved readability too, even though it made the merge tricky.
I haven't pushed out yet because it's still going through my build tests, but it should be out soon.
