From 613d70436c1aeda6843ca8b70c7fab6d0484a591 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 11 Oct 2007 17:44:08 +1000 Subject: [XFS] kill xfs_iocore_t xfs_iocore_t is a structure embedded in xfs_inode. Except for one field it just duplicates fields already in xfs_inode, and there is nothing this abstraction buys us on XFS/Linux. This patch removes it and shrinks source and binary size of xfs aswell as shrinking the size of xfs_inode by 60/44 bytes in debug/non-debug builds.
