Ok, right:

dax: dax_layout_busy_page() warn on !exceptional
https://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git/commit/?h=dev&id=cdbf8897cb09b7baf2b8a7e78051a35a872b01d5

ext4: handle layout changes to pinned DAX mappings
https://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git/commit/?h=dev&id=430657b6be896db57d974375cc499ca212c7f01d

I think the one I meant to ask about was:

[PATCH v2 1/2] ext4: Close race between direct IO and ext4_break_layouts()

https://patchwork.kernel.org/patch/10560393/

Sorry for the confusion.
