From 993386c19afa53fa54d00c7721e56ba820b3400d Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 28 Aug 2007 16:12:30 +1000 Subject: [XFS] decontaminate vnode operations from behavior details All vnode ops now take struct xfs_inode pointers and the behaviour related glue is split out into methods of it's own. This required fixing xfs_create/mkdir/symlink to not mess with the inode pointer but rather use a separate boolean for error handling. Thanks to Dave Chinner for that fix.
