Return enhanced basic attributes from the AFS filesystem. This includes the following: (1) The data version number as st_data_version. (2) STATX_INFO_AUTOMOUNT will be set on automount directories by virtue of S_AUTOMOUNT being set on the inode. These are referrals to other volumes or other cells. (3) STATX_INFO_AUTODIR on a directory that does cell lookup for non-existent names and mounts them (typically mounted on /afs with -o autocell). The resulting directories are marked STATX_INFO_FABRICATED as they do not actually exist in the mounted AFS directory. (4) Files, directories and symlinks accessed over AFS are marked STATX_INFO_REMOTE. Local fake directories are marked STATX_INFO_FABRICATED. (5) STATX_INFO_NONSYSTEM_OWNERSHIP is set as the UID and GID retrieved from an AFS share may not be applicable on the system. and also some auxiliary data: (6) The volume ID and type. (7) The volume name. (8) The cell name.
