From 4188c78d951d8a44630f4c33bc0f5b63374572a4 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 5 Feb 2008 12:13:53 +1100 Subject: [XFS] keep i_nlink updated and use proper accessors To get the read-only bind mounts in -mm to work correctly with XFS we need to call the drop_nlink and inc_nlink helpers to monitor the link count. Add calls to these to xfs_bumplink and xfs_droplink and stop copying over di_nlink to i_nlink in xfs_validate_fields and vn_revalidate.
