Fix the symlink code and leave a comment in the generic bmap code reminding us that the format-specific data copy needs to set the destination buffer type appropriately. cc: # 3.10 to current Tested-by: Jan Kara Signed-off-by: Dave Chinner Reviewed-by: Brian Foster Signed-off-by: Dave Chinner --- diff --git a/fs/xfs/libxfs/xfs_bmap.c b/fs/xfs/libxfs/xfs_bmap.c index b5eb4743f75a..4e20fe7497b3 100644 --- a/fs/xfs/libxfs/xfs_bmap.c +++ b/fs/xfs/libxfs/xfs_bmap.c @@ -973,7 +973,11 @@ xfs_bmap_local_to_extents( *firstblock = args.fsbno; bp = xfs_btree_get_bufl(args.mp, tp, args.fsbno, 0); - /* initialise the block and copy the data */ + /* + * Initialise the block and copy the data + * + * Note: init_fn must set the buffer log item type correctly! + */ init_fn(tp, bp, ip, ifp); /* account for the change in fork size and log everything */ diff --git a/fs/xfs/libxfs/xfs_symlink_remote.c b/fs/xfs/libxfs/xfs_symlink_remote.c index c80c5236c3da..e7e26bd6468f 100644 --- a/fs/xfs/libxfs/xfs_symlink_remote.c +++ b/fs/xfs/libxfs/xfs_symlink_remote.c @@ -178,6 +178,8 @@ xfs_symlink_local_to_remote( struct xfs_mount *mp = ip->i_mount; char *buf; + xfs_trans_buf_set_type(tp, bp, XFS_BLFT_SYMLINK_BUF); + if (!xfs_sb_version_hascrc(&mp->m_sb)) { bp->b_ops = NULL; memcpy(bp->b_addr, ifp->if_u1.if_data, ifp->if_bytes);
