I don't really care but you two > should agree :) fs/xfs/libxfs/xfs_fs.h is the XFS userspace API definition file and is shared with userspace (via xfsprogs, ends up at /usr/include/xfs/xfs_fs.h), and BBTOB() and BTOBB() are part of that API, hence they need to stay there. ISTR that you only need them in one place in the quota translation layer, so Christoph is right - it's probably best to simply open code them with an appropriate comment somewhere in the file to explain why....
