No local regular files

[Shailendra Tripathi <stripathi@xxxxxxxxx>]

Hi,
	I had an impression that XFS writes the data on the inode itself if 
data is pretty small. However, recently I came to know that for regular 
files it does not do the same, at least on Linux XFS.
xfs_iformat()
        ....
                         /*
                         * no local regular files yet
                         */
                        if (unlikely((INT_GET(dip->di_core.di_mode, 
ARCH_CONVERT
) & S_IFMT) == S_IFREG)) {
                                xfs_fs_cmn_err(CE_WARN, ip->i_mount,
                                        "corrupt inode (local format 
for regular
 file) %Lu.  Unmount and run xfs_repair.",
                                        (unsigned long long) ip->i_ino);
                                XFS_CORRUPTION_ERROR("xfs_iformat(4)",
                                                     XFS_ERRLEVEL_LOW,
                                                     ip->i_mount, dip);
                                return XFS_ERROR(EFSCORRUPTED);
                        }

	Am wondering what might be the reason for non-inclusion and whether it 
was ever implemented in XFS ? If implemented on IRIX XFS, what is 
potential reason for not being available on Linux ? Or, it is just that 
it does not give any benefit. I believe that there are significant 
number of such small files
