[Ocfs2-tools-devel] [PATCH 15/15] dx_dirs v10: enable metaecc and indexed-dirs support as default features

[Coly Li]

metaecc feature enables ECC checking for meta data, which helps the file
system consistency. indexed-dirs feature enables indexed tree for
directories, which improves lookup performance for large scale
directories.

This patch enables metaecc and indexed-dirs support as default features.
