Not your fault at all, Darrick!

I only complained about the xfs_buf typedef because it would cause
merge problems for ~80% of the patches in my current dev tree. This
was the only patch that the xfs_buf_log_item typedef removal
affected - more were affected by the trivial b_fspriv to b_log_item
changeover - and I figured that pain was worth it to get rid of
another typedef....

OK, nothing unusual, though I haven't been using sparse=1 recently.
I'll get onto it....

Cheers,

Dave.
