GFS2: Add structure to contain rgrp, bitmap, offset tuple
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. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
