Return enhanced file attributes from the AFS filesystem. This includes the
following:
(1) STATX_ATTR_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.
STATX_ATIME, STATX_CTIME and STATX_BLOCKS are cleared as AFS does not
support them.
Example output:
[root@andromeda ~]# ./samples/statx/test-statx /afs
statx(/afs) = 0
results=7ef
Size: 2048 Blocks: 0 IO Block: 4096 directory
Device: 00:25 Inode: 1 Links: 2
Access: (0777/drwxrwxrwx) Uid: 0 Gid: 0
Access: 2006-05-07 00:21:15.000000000+0100
Modify: 2006-05-07 00:21:15.000000000+0100
Change: 2006-05-07 00:21:15.000000000+0100
