Synopsis: vm_page_free frees wrong pages in vfs_bio.c

State-Changed-Why: 
This should be fixed in rev 1.82 of vfs_bio.c. The problem appears to
be that "from" is already aligned at the buffer base, but bp->b_data
was not. bp->b_data needs to first be page-truncated before the
subtraction. I've rewritten the routines in rev 1.82 and the new version
should fix the problem.
