Umm...  OK, but it won't be particulary pretty:
	* big one - consolidation of descriptor-related logics; almost all
of that is moved to fs/file.c (BTW, I'm seriously tempted to rename the
result to fd.c.  As it is, we have a situation when file_table.c is about
handling of struct file and file.c is about handling of descriptor tables;
the reasons are historical - file_table.c used to be about a static array
of struct file we used to have way back).   A lot of stray ends got cleaned
up and converted to saner primitives, disgusting mess in android/binder.c
is still disgusting, but at least doesn't poke so much in descriptor table
guts anymore.  A bunch of relatively minor races got fixed in process,
plus an ext4 struct file leak.
	* related thing - fget_light() partially unuglified; see fdget()
in there (and yes, it generates the code as good as we used to have).
	* also related - bits of Cyrill's procfs stuff that got entangled
into that work; _not_ all of it, just the initial move to fs/proc/fd.c
and switch of fdinfo to seq_file.
	* Alex's fs/coredump.c spiltoff - the same story, had been easier to
take that commit than mess with conflicts.  The rest is a separate pile, this
was just a mechanical code movement.
	* a few misc patches all over the place.  Not all for this cycle,
there'll be more (and quite a few currently sit in akpm's tree).
