Hi,

Please consider pulling the following changes,

Steve.

-----------------------------------------------------------------------

The major feature this time is the "rbm" conversion in the resource
group code. The new struct gfs2_rbm specifies the location of an
allocatable block in (resource group, bitmap, offset) form. There
are a number of added helper functions, and later patches then
rewrite some of the resource group code in terms of this new
structure. Not only does this give us a nice code clean up, but                 
it also removes some of the previous restructions where extents
could not cross bitmap boundaries, for example.

In addition to that, there are a few bug fixes and clean ups, but
the rbm work is by far the majority of this patch set in terms of
number of changed lines.
