Constant INLINE_CONTENT_MAX 

pub const INLINE_CONTENT_MAX: usize = 64;

All files that contain 64 or fewer bytes (size <= INLINE_CONTENT_MAX) should be stored inline in the erofs image (and also in splitstreams). All files with 65 or more bytes (size > MAX) should be written to the object storage and referred to from the image (and splitstreams).
