Hi all,

Here are some assorted bug fixes for 6.4:

 * A regression fix for the allocator refactoring that we did in 6.3.
 * Fix a bug that occurs when formatting an internal log with a stripe
   alignment such that there's free space before the start of the log
   but not after.
 * Make scrub actually take the MMAPLOCK (to lock out page faults) when
   scrubbing the COW fork
 * If we call FUNSHARE on a hole in the data fork, don't create a
   delalloc reservation in the cow fork for that hole.

v2: fix some comments that fell out of sync with the code

If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.

This is an extraordinary way to destroy everything.  Enjoy!
Comments and questions are, as always, welcome.
