autofs4: Merge the remaining dentry ops tables
Merge the remaining autofs4 dentry ops tables. It doesn't matter if d_automount and d_manage are present on something that's not mountable or holdable as these ops are only used if the appropriate flags are set in dentry->d_flags. [AV] switch to ->s_d_op, since now _everything_ on autofs4 is using the same dentry_operations. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
