The export_operations member ->encode_fh() has been updated to take both the child and parent inodes. This interface used to take the child dentry and a bool describing if the parent is needed. NOTE: While updating this code I noticed that we do not currently cleanly handle the case where we're passed a connectable parent. This code should be audited to make sure we're doing the right thing. Signed-off-by: Richard Yao <ryao@cs.stonybrook.edu> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Issue #784
