1 commentsI'm virtually certain that exposing that on disk struct to users had so much legacy code that struct dirent was just not worth updating when the capability of using multiple file systems got added to various kernels. We're stuck with it, an accident of history, just like we're stuck with FAT filesystems for boot partitions and similar.
