Hi,

as I've mentioned at LSF/MM [1], I think it would be nice if mm pull
requests had summaries similar to other subsystems. I see they are now
more structured (thanks!), but they are now probably hitting the limit
of what scripting can do to produce a high-level summary for human
readers (unless patch authors themselves provide a blurb that can be
extracted later?).

So I've tried now to provide an example what I had in mind, below. Maybe
it's too concise - if there were "larger" features in this pull request,
they would probably benefit from more details. I'm CCing the known (to
me) consumers of these mails to judge :) Note I've only covered mm, and
core stuff that I think will be interesting to wide audience (change in
LIST_POISON2 value? I'm sure as hell glad to know about that one :)

Feel free to include this in the merge commit, if you find it useful.

Thanks,
Vlastimil

I'll take it as a trial. I added one-line notes about coda and the

I put all pid{fd}/clone{3} which is mostly related to pid.c, exit.c,
fork.c into my tree and try to give it a consistent theme for the prs I
sent. And that at least from my perspective that worked and was pretty
easy to coordinate with Andrew. That should hopefully make it a little
easier to theme the -mm tree overall going forward.

Very much agree, that was also discussed at length in the LSF/MM mm
process session I've linked.

I'll check if the first patch bomb would be more amenable to that, as I
plan to fill in the mm part for 5.3 on LinuxChanges wiki, but for a
merge commit it's too late.

Nevermind the misc stuff that much, but I think mm itself is more
important and deserves what other subsystems have.

Perhaps now it would be nice if this went also to linux-mm and lkml, as

[This is going to sound awfully self-glorifying. Oh well.] I did point
that out in another instance (memparse), which I think then got somewhat
fixed in a later version. Since Alexey and I seemed to disagree on what
guiding principles to use when doing the conversions and a number of
other points, I didn't have the energy to go through the entire series,
and the discussion died out.

No.

I'm not taking yet another broken "deprecate old interface, replace it
with new-and-improved one, and screw things up in the process".

The whole "kstrto*()" thing was a mistake. We had real bugs brought in
by the conversion to the "better" interface. The "even betterer" new
parse_integer() interface actually looks lik ea real improvement, and
talks about some of the brokenness of the old code, and I was really
wanting to like it, but then I saw the conversions.

The VERY FIRST conversion patch I looked at was buggy. That makes me
angry. The whole *AND*ONLY* point of this whole thing was to get rid
of bugs, and be a obviously safe interface, and then the first
conversion patch proves it wrong.

Let me show you:

        if (isdigit(*str)) {
-               io_tlb_nslabs = simple_strtoul(str, &str, 0);
+               str += parse_integer(str, 0, &io_tlb_nslabs);

and obviously nobody spent even a *second* asking themselves "what if
parse_integer returns an error".

The old code didn't fail catastrophically in the error case. The new one does.

And yes, parse_integer() really can return an error, even despite that
"isdigit(*str)" check. Think about it. Or just read the source code.

I really am very tired indeed of these "trivially obvious
improvements" that are buggy and actually introduce whole new ways to
write buggy code. Yes, the old code could miss an error. But the old
code wouldn't then create invalid pointers like the new code does.

I'm not thrilled about going through the rest of this sequence,
looking for other gotcha's. But I am *really* really tired of this
idiotic "let's make up a new interface that gets things right" and
then absolutely doesn't get it right at all. This is not just an issue
for number parseing - we had similar issues with the completely
moronic and misdesigned crap called "strlcpy()", which was introduced
for similar reasons, and also caused nasty bugs where the old code was
actually correct, and the "converted to better and safer interfaces"
code was actually buggy.

Mixing the error handling and the string update was a mistake.
Although *not* mixing it causes its own set of problems.

But whatever the final resolution to this is, I am *not* taking this
series. No way, no how. I liked the automatic type-based templating it
does, but I *don't* like the breakage that seems to be inevitable in
any large-scale conversion from a previously used historical
interface. People who implement new and improved interfaces always
seem to get that wrong.

In fact this is the harmless sort (changes only the error code of a

Ah.  The patch affects security code, but it doesn't actually address any
insecurity.  I didn't think it was needed for -stable?



From: Roland McGrath <roland@redhat.com>

wait* syscalls return -ECHILD even when an individual PID of a live child
was requested explicitly, when security_task_wait denies the operation. 
This means that something like a broken SELinux policy can produce an
unexpected failure that looks just like a bug with wait or ptrace or
something.

This patch makes do_wait return -EACCES (or other appropriate error returned
from security_task_wait() instead of -ECHILD if some children were ruled out
solely because security_task_wait failed.

Serial drivers?  Well you saw me drop a bunch of them.  I now have:

serial-driver-pmc-msp71xx.patch
rm9000-serial-driver.patch
serial-define-fixed_port-flag-for-serial_core.patch
mpsc-serial-driver-tx-locking.patch

I'll also be holding off on MADV_FREE - Nick has some performance things to

I have some powerpc bits that depend on that stuff that will go through

So this is what I have lined up for the first mm->2.6.22 batch.  I won't be
sending it off for another 12-24 hours yet.  To give people time for final
comment and to give me time to see if it actually works.



- A few serial bits.

- A few pcmcia bits.

- Some of the MM queue.  Includes:

  - An enhancement to /proc/pid/smaps to permit monitoring of a running
    program's working set.

    There's another patchset which builds on this quite a lot from Matt
    Mackall, but it's not quite ready yet.

  - The SLUB allocator.  It's pretty green but I do want to push ahead
    with this pretty aggressively with a view to replacing slab altogether.

    If it ends up not working out then we should remove slub altogether
    again, but I doubt if that will occur.

    If SLUB isn't in good shape by 2.6.22 we should hide it in Kconfig
    to prevent people from hitting known problems.  It'll remain
    EXPERIMENTAL.

  - generic pagetable quicklist management.  We have x86_64 and ia64
    and sparc64 implementations, but I'll only include David's sparc64
    implementation here.  I'll send the x86_64 and ia64 implementations
    through maintainers.

  - Various random MM bits

  - Benh's teach-get_unmapped_area-about-MAP_FIXED changes

  - madvise(MADV_FREE)



  This means I'm holding back Mel's page allocator work, and Andy's
  lumpy-reclaim.

  A shame in a way - I have high hopes for lumpy reclaim against the
  moveable zone, but these things are not to be done lightly.

  A few MM things have been held back awaiting subsystem tree merges

sendpatchset has that, already builtin ;)

Though the 5 second delay might not be enough for someone
publishing at the rate Andrew does.

My sendpatchset tool should be good for this.  It sends all but the
first message are sent in "Reference" to, and "In-Reply-To" the first
message.

  http://www.speakeasy.org/~pj99/sgi/sendpatchset

I use it when sending out multiple patches in sequence from a quilt
repository.

The patch bombing seems to have really wedged vger.  It took up to 24
hours to get all the messages.

Looks like Andrew's patch bomb script needs some rate limiting ;-)

I just double-checked, and I can say that I received all 198 emails from 
vger...

I don't see a patch which adds linux/pm.h to linux/sysdev.h, which is
required to fix ARM builds in -rc2 and onwards kernels.

It is my understanding that you have such a patch, and if it isn't
going to be sent, I'd like to send my own fix so that ARM can start
building again in mainline.

Umm, what stops you from letting all the parts refer to part zero,

I'd like to second the idea of having all the patches be replies to this 
original posting (ie one level of indenting for all patches).  That way 
a threaded view will only have one subject line for all 198 patches.

I meant something like this:

[patch 000/100]  Foo-ize the baz.
   [patch 001/100] Frob the baz
   [patch 002/100] baz cleanups
   [patch 003/100] apply foo-ization to baz

Rather than

[patch 000/100] Foo-ize the baz.
   [patch 001/100] Frob the baz
     [patch 002/100] baz cleanups
       [patch 003/100] apply foo-ization to baz

Which would (as you rightly pointed out) be ludicrous.

i.e., all the patches are replys to the summary.

I never got around to setting that up, plus the Subject:s pretty quickly
become invisible when they're indented 198 columns in GUI MUAs.

Hopefully we'll have the commits list running next time...

Is there any chance that in the future that these patch sets get posted
all to one thread?  Perhaps as a reply to a summary? 1 thread to ignore
is preferable to 198.

As the commits list probably isn't working at present I'll cc linux-kernel
on this lot.  Fairly cruel, sorry, but I don't like the idea of people not
knowing what's hitting the main tree.



This is the first live test of Linus's git-importing ability.  I'm about
to disappear for 1.5 weeks - hope we'll still have a kernel left when I
get back.

- As we're still a fair way from 2.6.12 and things are still backing up,
  it's a relatively large update.

- Various arch updates

- Big x86_64 update, as discussed

- decent-sized ppc32, ppc64 updates

- big infiniband update

- very nearly the last batch of u32->pm_message_t conversions.  Some
  other bits of this will be sitting out in subsystem trees - this is just
  the stuff which doesn't overlap.

- the important fixes from the md, nfs4 queues

- other random fixes and things we probably want to have in 2.6.12.

- I'd draw especial Linus attention to:

	"fix crash in entry.S restore_all" and
	"pci enumeration on ixp2000: overflow in kernel/resource.c"
