+	file-has-acl: revert both recent changes, 80af92af and 95f7c57f
+	* lib/file-has-acl.c: While the 2011-10-03 change does fix the
+	ls -lL regression introduced in coreutils-8.12, it does so at the
+	cost of an additional stat call in the common case.  Besides, now
+	that the kernel change that prompted commit 95f7c57f has been reverted
+	(see https://bugzilla.redhat.com/show_bug.cgi?id=720325#c24)
+	we have no use for commit 95f7c57f, "file-has-acl: use
+	acl_extended_file_nofollow if available".
