From 45ba598e56fa9f77801e06432b50580d97994fa4 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 7 Dec 2007 14:07:20 +1100 Subject: [XFS] Remove CFORK macros and use code directly in IFORK and DFORK macros. Currently XFS_IFORK_* and XFS_DFORK* are implemented by means of XFS_CFORK* macros. But given that XFS_IFORK_* operates on an xfs_inode that embedds and xfs_icdinode_core and XFS_DFORK_* operates on an xfs_dinode that embedds a xfs_dinode_core one will have to do endian swapping while the other doesn't. Instead of having the current mess with the CFORK macros that have byteswapping and non-byteswapping version (which are inconsistantly named while we're at it) just define each family of the macros to stand by itself and simplify the whole matter. A few direct references to the CFORK variants were cleaned up to use IFORK or DFORK to make this possible.
