Don't inherit default layout from root for new subdirectories

Details

    • 9223372036854775807

    Description

      There is no need to inherit the default directory layout from the root directory when subdirectories are created therein. This consumes xattr space on the subdirectories, and makes it more complex to change the filesystem default layout in the future.

      Instead, it should be possible to check if the parent directory is the root directory and not copy the default layout xattr to the new subdirectory.
