Ok, I think I'm getting close to releasing a real 2.6.23. Things seem to have calmed down, and I think Thomas Gleixner may have found the suspend/resume regression that has dogged us for a while, so I'm feeling happy about things. Of course, me feeling happy is usually immediately followed by some nasty person finding new problems, but I'll just ignore that and enjoy the feeling anyway, however fleeting it may be. The shortlog really is pretty short, and I'm appending the diffstat at the ...

On Tue, 25 Sep 2007 02:13:42 +0200 How much memory did you have in "cached" when you looked with top (and no swap enabled) ? If the amount of "cached" memory is very low, it could mean that your shared libraries are being pushed out of memory, instead of the kernel swapping out some page that belongs to only one process. As for kswapd getting into uninterruptible sleep state, it will do that all by itself sometimes, without even having any disk IO going on... that code looks a little suspect,...

Yup, I think I ditched most of them.. for some reason I decided it couldn't happen, but maybe I'm wrong ? Cheers, -

Fair enough. Ben. -

Device Initiated Power Management, which is defined in SATA 2.5 can be enabled for disks which support it. This patch enables DIPM when the user sets the link power management policy to "min_power". Additionally, libata drivers can define a function (enable_pm) that will perform hardware specific actions to enable whatever power management policy the user set up for Host Initiated Power management (HIPM). This power management policy will be activated after all disks have been enumerated and ...

Here's a set of patches which implement link power management for SATA. We had talked at kernel summit of moving sysfs interface for setting the link power management policy to the block layer, but after a lot of consideration, I think this doesn't make sense. Mainly because I feel for SATA the link power management policy should be associated with the controller, not with the device. So, we continue to use the shost_attrs array in the scsi host template to create a sysfs interface that is associa...

I'm seeing lockdep warning about a potential lock inversion between &mm->mmap_sem and &inode->i_mutex in NFS (see attachment). Unfortunately the basis for the warning appears to be the behaviour in ext3(???). AFAICS there is no way for NFS to share an inode->i_mutex with ext3. What to do? Trond

This is RFC patch 2/2.

Yes, hopefully the kprobes people will chime in here sometime and merge those as well, or just ack them and I can change the code. Thanks. --- ~Randy Phaedrus says that Quality is about caring. -

samples/Kbuild should be renamed to samples/Makefile. Sorry about that. I made the kprobes files build only as modules. You are probably attempting to build markers built-in, not as modules? That needs some makefile foo, I think. Sam?? -- ~Randy Phaedrus says that Quality is about caring. -

No, i did not manage to improve (it should NOT be a dangerous error BTW). I simply think that this issue is because of buggy firmware, so i posted to linux-ide a patch to blacklist this hard disk from using NCQ (because it is triggering spurious completions). I don't know what the "blacklisting policy" is for linux kernel developers, i think that, since there probably are a lot of buggy drives for NCQ and so, a module parameter to disable NCQ while loading libata could be useful. Best regards. ...

Does this have anything to do with idle balancing ? I noticed some fairly large latencies in that code in 2.6.23-rc's .. Daniel -

yeah, please pull that one. linux-2.6-sched.git by mistake contained an older sched-devel tree for about a day (where your scripts picked it up). I've restored that one to -rc7 meanwhile. It's only supposed to contain strict fixes for upstream. (none at the moment) Ingo -

while we're at it, we could change this to if (!(c->x86_vendor == X86_VENDOR_AMD && c->x86 == 5 && You could also use the max macro here: max(tx, 1) -

It's not inverting the test, so you don't need to move code. It evaluates the same, only the combined negation is moved to the front. I suggested it to increase clarity, it results in the same assembly language. Roel -
