have some issue with kmap() change on kmap_local_page(), then, as far as I 
can see, the root of issue should be kmap_local_page() but not HFS+ code. 
Oppositely, if it’s some undiscovered HFS+ issue, then again 
kmap_local_page() changes nothing. But I am OK if it is separate patches 
too.

And I am OK with sending a patchset :-)

I'm sorry because, while working on the last conversions for HFS+ in 
btree.c, I just noticed that I had overlooked one other kmap() call site in 
bitmap.c.

Therefore, I'd like to ask to drop this patch and I'll also ask to drop the 
patch to bnode.c in the related thread. 

When done, I'll send a series of three patches, one per file (bnode.c, 
bitmap.c, btree.c).

Thanks,

Fabio
