      Description

      Now that e2fsprogs-1.44.3 has support for large_dir, testing and enabling the large_dir support on MDTs would allow single directories to exceed the ~10M limit currently imposed by the 2-level htree. This should be done automatically for new MDTs, and the existing error message in ext4_dx_add_entry() should be updated to directly reference the large_dir feature by name instead of just "Large directory", and explain that it should be enabled by tune2fs.
