From 349457ccf2592c14bdf13b6706170ae2e94931b1 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Fri, 8 Sep 2006 14:22:21 -0700 Subject: [PATCH] Allow file systems to manually d_move() inside of ->rename() Some file systems want to manually d_move() the dentries involved in a rename. We can do this by making use of the FS_ODD_RENAME flag if we just have nfs_rename() unconditionally do the d_move(). While there, we rename the flag to be more descriptive. OCFS2 uses this to protect that part of the rename operation with a cluster lock.
