    GFS2: Add structure to contain rgrp, bitmap, offset tuple · 4a993fb1

    This patch introduces a new structure, gfs2_rbm, which is a
    tuple of a resource group, a bitmap within the resource group
    and an offset within that bitmap. This is designed to make
    manipulating these sets of variables easier. There is also a
    new helper function which converts this representation back
    to a disk block address.
    
    In addition, the rbtree nodes which are used for the reservations
    were not being correctly initialised, which is now fixed. Also,
    the tracing was not passing through the inode where it should
    have been. That is mostly fixed aside from one corner case. This
    needs to be revisited since there can also be a NULL rgrp in
    some cases which results in the device being incorrect in the
    trace.
    
    This is intended to be the first step towards cleaning up some
    of the allocation code, and some further bug fixes.
