If anyone has any objections, please let me know. ------------------ From: Dave Chinner [ Upstream commit d2fe5c4c8d25999862d615f616aea7befdd62799 ] The code to initialise, release and free items is all the way down the bottom of the file. Upcoming fixes need to these functions earlier in the file, so move them to the top. There is one code change in this move - the parameter to xfs_buf_item_relse() is changed from the xfs_buf to the xfs_buf_log_item - the thing that the function is releasing.
