Does inline data introduce a new mount option of some kind, or is it automatically enabled?
And what happens if the filesystem has inline data in some files, but the kernel doesn't support it? Does it refuse to mount such a filesystem?

Looking at the code, it looks like it creates a new ext4 "incompatible feature". That is, you will be able to specify it using `mke2fs -O <whatever>`, but then you will not be able to mount this filesystem in an older kernel, not even read-only, as it is marked as *incompatible*.
Now, I don't know if it will be enabled by default or if it will be changeable with `tune2fs`... more code reading required.

That makes sense.
Thanks for checking the code.
