Based on the location of the file patched, it this would seem to be 
targeted at the 2.6.18 tree, but then 2.6.18 does not have a
revalidate_disk() function (introduced only in .28). What's the deal
here? Should this perhaps be carried out by open coding in blkfront
what .28 does?

Thanks, Jan

Jan,

This patch was tested only on the 2.6.32 kernel. For kernels that don't support 
revalidate_disk, we may have to implement something equivalent. I will look at 
this later in the week.

I am attaching a new patch that is the delta on the previous one.
