Typically, when following absolute redirect, if an opauqe dentry is found, lookup in further lower directories is stopped. But if a child dentry has another absolute redirect, then lookup in further lower layers should continue. Say, following is example setup. upper: /redirect (redirect=/a/b/c) lower1: /a/[b]/c ([b] is opaque) (c has absolute redirect=/a/b/d/) lower0: /a/b/d/foo "redirect" directory in upper should merge with lower1:/a/b/c/ and lower0:/a/b/d/, despite lower1:/a/b/ being opaque. This example and kernel fix has come from Amir Goldstein. I am just putting a test for it to make sure its not broken down the line.
