Hi,
Is anybody working on/planning  to support UFS2 filesystem 
( of FreeBSD 5.x ) in Linux ?
As far as I understand , even ufs support is read only (not quite stable ).
Anybody working in this area ? Or should I  try to get my hands dirty ?

Niraj

Hi Andrew

What are your intentions with -mm when you take over 2.6? Is any of -mm 
getting into 2.6 before 2.6.0 release? Is it mainly queued for 2.6.1?

Will you be "bleeding edge" maintainer aswell or will that be handed

We'll start merging it up after 2.6.0.  It'll be quite a lot of work,
actually - a lot of things have been parked in -mm for some time and may
not have had sufficiently wide testing, especially on non-i386.  I need to
ask the originators and others to re-review and retest some things.

I guess I'll keep -mm going until there's a reason not to.

I'm getting the some thing. I think the file
asm-generic/cpu_mask_const_value.h is not included (this file have the

Hullo Andrew,
	I believe this was the intention;

For ES7000 add an offset of 16 to the irq in order to setup a mapping where
ISA/legacy interrupts are in the 0-15 range and PCI 16 and above. This was
a cleanup fix in order to facilitate easy differentiating between legacy
and non legacy interrupt setup.

===
The ES7000 merge added a bit of code of offset the IRQ numbers.  We're not
too sure why; it wasn't changelogged.

But it broke other systems, so this patch arranges for that code to only be
activated on es7000 machines.

ppp_asynctty_receive() is called from hard IRQ context and hence may not use
spin_unlock_bh().  The patch converts ppp to use an IRQ-safe spinlock.

... which only pushes the problem down one level, since
ppp_async_input eventually calls ppp_input with interrupts disabled,
which is not allowed.  The reason that it isn't allowed is that it
would mean that the ppp_generic code would have to disable interrupts
in its critical sections, which would be very bad for interrupt
latency, particularly if you are using compression or encryption on
the link.

Given the number of serial drivers that want to call the line
discipline receive_chars routine with interrupts hard-disabled, I
would consider a patch to ppp_async.c to make it use a tasklet so that
it calls ppp_input from softirq level.  But the currently proposed
patch is buggy.

Regards,
Paul.

Quite frankly I am becoming concerned about the number of patches that are 
queued for post 2.6.0.  It is beginning to look like 2.6.0 might be nice 
and quiet while 2.6.1+ are going to be quite messy as all the things "on 
hold" get put in.

I'm going to do my part by pounding heavily on -mm kernels since that 
appears where all this is ending up.

Well, most of these things do address real problems.  It's a matter of
feeding them in at an appropriate rate and with a higher level of testing.

That would be useful.  Testing on non-ia32 platforms remains a concern.  I
test on ia64 and ppc64, but I'm not aware of anyone regularly testing -mm
things on other architectures.

I've tested regularly on x86_64 (which I think is more important than
both ia64 (who cares) and ppc64). I'll start doing that again.

"User" report: I've had lost of stability problems with 2.6-test*,
including 2.6.0-no_test, on my laptop. Stuff like misplaced characters
in Galeon, crashing Konsole, inexplicable delays in pan, et al., which
never happened with 2.4.

For what it's worth, these seem to be gone for good since I rebooted into
-mm1 this morning. So, thanks to whoever's responsible for the patch that
actually fixed the problem.


If somebody _really_ needs to know, I can try to binary-search for the
patch that's responsible, but it'd take a month to find out anything
conclusive -- ten reboots, two days of stress testing each in order to
eliminate false positives, and a few days of no-computer-please,
I-need-a-holiday time. Thus, I'd rather not.


I've stored a Bitkeeper archive of the -mm1 patches (one changeset per
patch) to bk://smurf.bkbits.net/linux-2.6-mm, for those (like me ;-)
who don't like to work with patches. I'll keep that up-to-date so that
there's a clean upgrade path.

It would be good to even get a "good hint", even if it won't be 
conclusive. Even if it starts out as just a list of "this patch can't 
matter, because it's not active in my configuration", and perhaps then 
specified a bit better afterwards..

I'll try to narrow it down somewhat. Unfortunately, the nature of binary
search is so that even if I manage to declare half of the patches as
irrelevant, that doesn't help much.

[ time passes while I forgot to send this message ]

Oh happiness. :-/  At least part of the bug (galeon misplaces text) still
exists, as it turns out, though it's a lot harder to trigger with
2.6.0-mm1. Since the galeon thing was usually the first Special Effect to
show up, this may well be two different bugs -- and I'm not ruling out an
application problem.
