Subject: [PATCH] xfs: report crtime and attribute flags to statx
Date: Mon, 6 Mar 2017 16:06:09 -0800	[thread overview]
Message-ID: <20170307000609.GG5280@birch.djwong.org> (raw)

statx has the ability to report inode creation times and inode flags, so
hook up di_crtime and di_flags to that functionality.
