I scratched my head reading:

in xfs_attr_leaf.h:
/*
  * Used to keep a list of "remote value" extents when unlinking an inode.
  */
typedef struct xfs_attr_inactive_list {
	xfs_dablk_t	valueblk;	/* block number of value bytes */
	int		valuelen;	/* number of bytes in value */
						     ^^^^^
						     |||||
} xfs_attr_inactive_list_t;

Where "valuelen" is clearly being used as blocks. A more obvious name is
the former "valueblk". Blame commit d7929ff6 for the confusion. Should 
change
the comment and/or variable one of these days ...
