Yeah, and the simple fix (lock in xfs_bmap_rtalloc()) uncovers
further issues w.r.t. logging - the buffers are not stamped with a
type, so log recovery will not categorise them correctly.

And, I suspect, log recovery might have problems with the
bitmap/smmary buffers as they don't have magic numbers in them. More
work to be done here...

Cheers,

Dave.
