Also in hfsplus_fs.h there are:

====> snip <=====
#define hfs_btree_open hfsplus_btree_open
#define hfs_btree_close hfsplus_btree_close
#define hfs_btree_write hfsplus_btree_write
#define hfs_bmap_alloc hfsplus_bmap_alloc
#define hfs_bmap_free hfsplus_bmap_free
#define hfs_bnode_read hfsplus_bnode_read
...
====> snap <=====

Does these exist for some legacy reason or does it serve any other
purpose ?. The only usage I see is that they change function names after
pre-processing.

Thanks a lot,

Best regards,
Sougata.
