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

These are parameters to xfs_da_{get,read,reada}_buf, please put them
next to the declarations for those functions.

Also they probably ought to be explicitly cast to xfs_daddr_t, e.g.

/* Force a fresh lookup for the dir/attr mapping. */
#define XFS_DABUF_MAP_NOMAPPING	((xfs_daddr_t)-1)

/* Don't complain if we land in a hole. */
#define XFS_DABUF_MAP_HOLE_OK	((xfs_daddr_t)-2)

I think this misses the xfs_dir3_data_read call in
xfs_dir2_leaf_to_block?

...and two more dir3_leaf_read calls further down in this function...

I also noticed missing conversions for xfs_dir3_data_read in
xchk_dir_rec, xchk_directory_data_bestfree,
xchk_directory_leaf1_bestfree, and xchk_directory_free_bestfree.

There's also a missing xfs_dir3_data_readahead conversion in
xchk_parent_count_parent_dentries in fs/xfs/scrub/parent.c.

...more missing conversions of xfs_dir3_data_read in
xfs_dir2_leaf_readbuf; and of xfs_dir3_data_readahead in
xfs_dir2_leaf_readbuf...

...and a missing conversion of xfs_dir3_data_readahead in xfs_dir_open
in fs/xfs/xfs_file.c.

Hmm, I dont see that these are declared in a header file, but how about 
fs/xfs/libxfs/xfs_da_btree.h ?  Did I miss them somewhere?
