Indeed you were, and let me try to answer it as best I can. I like to think of the "block layer" as two main parts. Firstly there is the "interface" which it defines, embodied primarily in generic_make_request() and 'struct bio'. There are various other small routines in ll_rw_blk.c, and there is 'struct request_queue' which is also involved in the other half of the block layer. This interface defines how requests are passed down, how their completion is acknowledged, and various other littl...

If the SCM stores some tags in special places, that is fine with me. The remove the need for the tag and an understanding of why it exists. My understanding of Andrew Morton's position on s-o-b is that it is an unordered set. I know this because when I have sent him patches with a proper From: line, he has complained and begrudingly took the first s-o-b, but said he didn't like to. So there seems to be disagreement on this (I think it looks like a I'm failing to follow your logic. You seem to...

The kernel newbies community often gets inquiries from CS students who need a project for their studies and would like to do something with the Linux kernel, but would also like their code to be useful to the community afterwards. In order to make it easier for them, I am trying to put together a page with projects that: - Are self contained enough that the students can implement the project by themselves, since that is often a university requirement. - Are self contained enough that Linux could...

Hi, Thanks, looks reasonable, but patch does not apply cleanly to mainline or -mm. (trivial to fix) --- ~Randy -

This patch appears trivially correct to me. -

Hello, Adding to his question, I am interested in doing a PhD in Operating Systems. Would anybody have some information on a similar list of labs and/or Universities that host projects related to Linux? Thanks in advance. Guilherme -

I think Greg wrote a paper on this subject, so I've added him to CC in case he has the link handy. -- Cheers, Alistair. 137/1 Warrender Park Road, Edinburgh, UK. -

The code looks correct, but I think it would be nicer to change hrtimer_nanosleep to take a kernel pointer and have all three callers (common_nsleep, sys_nanosleep and compat_sys_nanosleep) do the copy_to_user/put_compat_timespec in the caller. This would also make it possible to get rid of set_fs() in compat_sys_clock_nanosleep(). Arnd <>< -

Since upgrading to 2.6.23.1 from 2.6.23-rc9, resume-from-RAM has been misbehaving here. It takes much (+5-7 seconds) longer to resume *sometimes*, but not all/most of the time. And sometimes I get get flashing keyboard LEDs and have to hold the power button in for a full hard reset. With 2.6.23-rc8/rc9, no such troubles. Difficult to reproduce, other than perhaps once a day. Anybody want to fess up with a likely candidate? Dell Inspiron 9400 Core2duo + 2GB RAM, 32-bit x86 kernel+user. .con...

Yeah, I didn't see much there either. I'll keep an eye on things over the next few days, and post again if it persists. I was using the powertop patches with -rc9, but not with 2.6.23.1. Maybe they helped (???). -ml -

What's with all these odd formats, and where is .zip? :) Somehow... have you tried lrzip? Furthermore, if the files in the .tar archive were actually sorted.. (Obviously we shall pick .7z) -

For compression with -mx=9 it does use 500-900 MiB of RAM, that is true. For decompression, 50-70 MiB. Each have their pros/cons but nothing can compress the kernel any further than 7z, supports stdin/stdout and also has a native windows port. I used to strictly use bzip2 for backups and such but if I can pick off an additional 20-30% more than bzip2 for my backups which I will not use often, 7zip seems to be the winner for space savings and possibly for bandwidth/cost savings.. compr...

It uses 2 cores (multi-thread/multi-core), I believe the author of 7z (I asked him about this before) said the compression algorithm can use 1.8-2.2 cpus. Justin. -

I build linux-2.6.23-mm1 and try to boot it using qemu, and it crashed with trace like this: do_page_fault error_code lock_acquire _spin_lock_irqsave gdth_timeout run_timer_softirq __do_softirq do_softirq I have screenshot, but have no idea, is it legal to include it, if I sent copy to lkml. config of kernel in attachment, I apply all three patches from hot-fixes.

(please don't top-post! edited...) I didn't notice that qemu was involved. Does qemu have an emulator for the gdth hardware? -

There's a bug in the gdth rework in that the instance can be deleted from the list before the actual timer is stopped. This can be worked around I think by the following patch; although we really should be stopping the timer from firing when the list goes empty.
