No cute April 1st shenanigans, just a regular -rc release that happened to 
come up today because I was waiting for the input layer oops-fixes to be 
ready and tested.

I think the dirstat continues to be fairly informative, with arch/ and 
drivers dominating as usual. And within arch, a fair amount of the line 
noise are all those defconfigs. I wish we had some saner way of handling 
that, but apart from causing noise in the statistics there aren't any real 
downsides. Anyway, here is:

	  15.2% arch/mips/configs/
	  17.5% arch/mips/
	   2.3% arch/powerpc/configs/
	   3.1% arch/powerpc/
	   7.8% arch/sparc64/kernel/
	   8.1% arch/sparc64/
	   4.3% arch/x86/kernel/
	   2.0% arch/x86/lguest/
	   3.2% arch/x86/mach-rdc321x/
	  11.0% arch/x86/
	  40.6% arch/
	   2.2% drivers/char/
	   2.6% drivers/lguest/
	   2.3% drivers/net/igb/
	   8.7% drivers/net/netxen/
	   2.1% drivers/net/phy/
	  15.8% drivers/net/
	  30.6% drivers/
	   4.7% fs/
	   5.0% include/asm-sh/
	   8.6% include/
	   3.9% net/
	   7.5% scripts/

but the bulk of the fixes are the usual random one-liners. Some of the 
"bulk" above (like the arch/x86/kernel changes) are actually just moving 
some functions around in a file, so they look like larger diffs than they 
actually are.

A lot of the one-liners are some sparse cleanups, which is probably 
unnecessary noise at this point, but when Al sends me a series I just tend 
to apply it because his patches tend to be rather careful and basically 
always correct.

The big thing that is actually *noticeable* to most people is that this 
should fix the two top regressions: we've had some suspend-resume 
regressions due to the stupid ACPI _PTS orderign issues, and while the 
cleanups were left, the ordering changes were reverted. So that should fix 
issues for some people (of course, the people who had it fixed are 
unhappy, but regressions are worse).

The other thing that bit a number of people and is now fixed (and that 
also probably often showed up as a suspend/resume regression) was some 
"struct device" lifetime changes that broke the input layer. Thanks to 
people who debugged that one.

So give it a test. And update your regression entries..

The downside is that at least some of these were already pending in
maintainers trees for 2.6.26 (among other changes) and so have now caused
(unnecessary) merge conflicts.  Is there some reason that these fixes
can't go through the subsystem trees (especially once we get past rc1 (or
2) and people are gearing up for the next merge window)?

I don't think it's necessarily a bad idea to go through subsystem trees, 
but on the other hand I also don't think it should necessarily be a goal 
in itself.

For example, we had a patch-series from Roland McGrath that was apparently 
almost entirely based on the fact that going through (and getting 
sign-off) from all the architecture maintainers for his ptrace changes was 
just painful as hell for him.

At that point, when there is somebody like Roland who knows the rare and 
odd ptrace interfaces, having him jump through hoops just to go through 
"proper channels" is in my opinion just anti-productive (especially since 
I also think the "political" aspect of the problem causes the actual 
technical side of the patches to suffer - because they are more about 
the politics than about the technology).

So at some point, subsystem mainteinance should also be about picking up 
and handling the changes that come the other way. The kernel development 
isn't a strict hierarchy, and shouldn't be - it's more of a network of 
trust.

In other words, there are people I think are generally trusted across most 
maintenance borders. Al, as far as I'm concerned, is one of them.  
Especially sicne he is also one of the few people who clearly not only 
does run sparse but also looks at the code and actually fixes real bugs 
with byte order etc - regardless of where it is (ie he works across 
drivers, filesystems, an arch-specific code)

In other words, I don't think the borders are so tightly drawn, and the 
same way I trust the individual developers who send me patches (and git 
trees) rather than whatever _companies_ they happen to work, I also tend 
to trust individual developers rather than the _subsystem_ that they 
happen to maintain.

Of course, there's often a rather direct mapping between the two, where 
people naturally have the area they work in. But some people cross across 
any particular area, and while that tends to be unusual, that very much 
includes people like Andrew and Al.

In other words, at least to me it's not about "person X maintains file Y". 
It's much more about "I trust person X (perhaps within parameters Z)". And 
I don't think that's even unusual or even really unexpected.

And I think that's how we all work (and how we _should_ work), but 
sometimes people get so used to the fact that some people are fairly 
tightly associated with certain code that they think it's about the 
subsystem, not about the person.

Btw - don't get me wrong - we clearly do try to (and should) make merges 
easy, and it's why the kernel source code is generally pretty modular and 
we try to keep things as independent as possible. I'm not at all arguing 
against that.

I'm just trying to explain that at least personally, I just don't see that 
"modularity" and maintainership as a _primary_ issue. The primary issue is 
just the interpersonal trust people build up over time. The modularity and 
trying to keep borders is about practical concerns, and it's important 
too. But it is still secondary, I think.
