[Linux-cachefs] ext4 and NTFS support?

[Rince]

I'd expect ext4 to work with cachefilesd if ext[23] do. I know it works as a
backing store.

Using NTFS as a backing store isn't reasonable at present because ntfs-3g
doesn't do permission handling in any sane fashion, much less xattrs, so it
won't Do The Right Thing(tm).
