From f87d39d951329cd8f462bf9007d334122c0599d0 Mon Sep 17 00:00:00 2001 From: Steve French Date: Fri, 27 May 2011 03:50:55 +0000 Subject: [CIFS] Migrate from prefixpath logic Now we point superblock to a server share root and set a root dentry appropriately. This let us share superblock between mounts like //server/sharename/foo/bar and //server/sharename/foo further.
