This patch adds two new defines XFS_DABUF_MAP_NOMAPPING and XFS_DABUF_MAP_HOLE_OK. This helps to clean up hard numbers and makes the code easier to read Signed-off-by: Allison Collins <allison.henderson@xxxxxxxxxx> --- fs/xfs/libxfs/xfs_attr.c | 14 +++++++----- fs/xfs/libxfs/xfs_attr_leaf.c | 23 +++++++++++-------- fs/xfs/libxfs/xfs_attr_leaf.h | 3 +++ fs/xfs/libxfs/xfs_da_btree.c | 50 ++++++++++++++++++++++++++++-------------- fs/xfs/libxfs/xfs_dir2_block.c | 6 +++-- fs/xfs/libxfs/xfs_dir2_data.c | 3 ++- fs/xfs/libxfs/xfs_dir2_leaf.c | 9 +++++--- fs/xfs/libxfs/xfs_dir2_node.c | 10 +++++---- fs/xfs/scrub/dabtree.c | 6 ++--- fs/xfs/scrub/dir.c | 4 +++- fs/xfs/xfs_attr_inactive.c | 6 +++-- fs/xfs/xfs_attr_list.c | 16 +++++++++----- 12 files changed, 97 insertions(+), 53 deletions(-) diff --git a/fs/xfs/libxfs/xfs_attr.c b/fs/xfs/libxfs/xfs_attr.c index b77b985..5cb83a8 100644 --- a/fs/xfs/libxfs/xfs_attr.c +++ b/fs/xfs/libxfs/xfs_attr.c @@ -591,7 +591,8 @@ xfs_attr_leaf_addname( */ dp = args->dp;
