From f8d55aa0523ad0f78979c222ed18b78ea7be793a Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Tue, 9 Feb 2016 16:54:58 +1100 Subject: xfs: introduce inode log format object We currently carry around and log an entire inode core in the struct xfs_inode. A lot of the information in the inode core is duplicated in the VFS inode, but we cannot remove this duplication of infomration because the inode core is logged directly in xfs_inode_item_format(). Add a new function xfs_inode_item_format_core() that copies the inode core data into a struct xfs_icdinode that is pulled directly from the log vector buffer. This means we no longer directly copy the inode core, but copy the structures one member at a time. This will be slightly less efficient than copying, but will allow us to remove duplicate and unnecessary items from the struct xfs_inode. To enable us to do this, call the new structure a xfs_log_dinode, so that we know it's different to the physical xfs_dinode and the in-core xfs_icdinode.

Now that we no longer log the struct xfs_icdinode directly, we don't need to keep the timestamps in this structure. instead we can copy them straight out of the VFS inode when formatting the inode log item or the on-disk inode. This reduces the struct xfs_inode in size by 24 bytes.

This reduces the size of the struct icdinode from 152 bytes to 88 bytes, and removes a fair chunk of unnecessary code, too.
