> This patch will take a previously unused bit in the 16-bit {{FsPermission}} and use it
to indicate the presence of an ACL on the file or directory.  The CLI will use this to display
an indicator in the permission string if an ACL is present.  The NameNode will use it in ACL
modification APIs, permission checks, and display of an indicator in the directory browser
web UI.
