    xfs: more do_div cleanups · 4f1adf33
    Eric Sandeen authored
    On some architectures do_div does the pointer compare
    trick to make sure that we've sent it an unsigned 64-bit
    number.  (Why unsigned?  I don't know.)
    
    Fix up the few places that squawk about this; in
    xfs_bmap_wants_extents() we just used a bare int64_t so change
    that to unsigned.
    
    In xfs_adjust_extent_unmap_boundaries() all we wanted was the
    mod, and we have an xfs-specific function to handle that w/o
    side effects, which includes proper casting for do_div.
    
    In xfs_daddr_to_ag[b]no, we were using the wrong type anyway;
    XFS_BB_TO_FSBT returns a block in the filesystem, so use
    xfs_rfsblock_t not xfs_daddr_t, and gain the unsignedness
    from that type as a bonus.
