I think this lock is causing a performance hit to my application. If there isnt any safe way without it then thats fine but just thought I would check.The first thread uses this fuction to add elements to the list. Full source here. [URL]

View 5 Replies View RelatedI've got a shared (Windows/multiuser Linux) laptop, and I've got installed World of Warcraft and some steam games in Windows. With steam games, there is (almost) no problems. I've installed steam in Linux, and soft linked the 'steamapps' directory (per-game compatibility is another issue). With WoW, the problem is different. I would like to have almost (but not) all files. Under World of Warcraft, every file and directory must be linked except the Interface directory and WTF/config.wtf file (so every user can play with their own settings and addons). How can I have a mix of linked and not linked files without linking every file? If I link manually every file/dir, when updating from Linux other users and Windows Wow is not updated; when updating from Windows, new files remains "unlinked".

I hacked together this script to rsync some files over ssh. The --remove-source-files option of rsync seems to remove the files it transfers, which is what I want. However, I also want the directories those files are placed in to be gone as well. The current part of the find command, -exec rmdir -p {} ; tries to remove the parent directory (in this case, /srv/torrents), but fails because it doesn't have the right permissions. What I'd like to do is stop rmdir from traversing above the directory find is run in, or find another solution to get rid of all the empty folders. I've thought of using some kind of loop with find and running rmdir without the -p switch, but I thought it wouldn't work out. Essentially, is there an alternative way to remove all the empty directories under the parent directory?

Does anyone know how to get the path with a inode number by C programming?
Or can I get the absolute path without giving a "path" but a inode number by C?

View 6 Replies View RelatedI write the network driver. Transmission of packets in user space I do through netlink socket`s. In user space there is a handling of packets and their transmission on other device (however, it isn't important).
Problem in that any time, packets through the driver in system, and is reverse, are transferred normally. But then there comes the moment when the kernel crash. If to look in syslog it seems to me that comes deadlock. Also I think that it is related with netlink socket`s.
I can't find the information on that anywhere how correctly to use netlink socket`s in kernel space. Can at you will any a reason into the account of synchronization of sockets and the driver in kernel space?
I can give the driver code if it is necessary.
I am not new to Debian and used to use commands like "apt-get install <package>", "apt-get update", "apt-get upgrade" and "apt-cache search <string>" regularly. But I never understood those Debian programs and the Debian package system with it's numerous programs and way to install things and work on software and configurations. Now, I just wanted to do something that I thought to be really easy. Get the source of an existing package. And despite spending over 3 hours - including reading the man-pages of commands - I cannot find a way!
Two things:
dpkg --get-selections | grep openvz
linux-image-2.6-openvz-amd64 install
linux-image-2.6.26-2-openvz-amd64 install
I already don't understand why I have two such packages installed. I would like to download the source of my kernel: apt-get source linux-image-2.6.26-2-openvz-amd64. This downloaded linux-2.6_2.6.26-21lenny4.dsc, linux-2.6_2.6.26.orig.tar.gz and linux-2.6_2.6.26-21lenny4.diff.gz
Then, I wanted to patch this - having found no explanation, I did:
cd linux
patch < ../linux-2.6_2.6.26-21lenny4.diff
That seemed to patch the kernel. But I am not sure - there are new files like this now_
[...]
Only in linux-2.6-2.6.26: xenctrl-capabilities.patch
Only in linux-2.6-2.6.26: xenctrl.patch
Only in linux-2.6-2.6.26: xenctrl-privcmd.patch
[...]
So, how can download the complete Debian kernel source? And what do I need to be able to compile it? And - HOW to just list all available sources and search in them?!? I found lots of webpages where tools like "make-kpkg" are used, which I do not understand again. Under SuSE, I could just select the package from a list, say "make oldconfig install modules modules_install" and be ready. Under Debian, I just find no way ...
I'm trying to compile a kernel for my Crux Linux install. I figured I'd do a 'make defconfig' to setup a .config file with the default configuration and then try to add anything I will need for my specific system. I found a script that scans my system and prints out a list of any current modules I am using. That way I can make sure to add these to my new kernel. It looks something like this:
Code:
ac.ko.gz
agpgart.ko.gz
ata_generic.ko.gz
ata_piix.ko.gz
battery.ko.gz
button.ko.gz
compal-laptop.ko.gz
dcdbas.ko.gz
dell-laptop.ko.gz
drm_kms_helper.ko.gz
drm.ko.gz
ehci-hcd.ko.gz
Is there a way to add these to my current configuration without having to go into 'make menuconfig' and search for each one? It's not too hard to search for many of them. But the ones with short names I'm not finding. Like ac.ko for example. 'ac.ko' returns 0 search results and 'ac' returns anything and everything with those 2 letters in it.
where I can find a list of Fedora 9 kernel updates (i.e. the updates that come through yum update) along with the dates they were released? I'd like to know when the last kernel I have installed (2.6.25.14-108.fc9.x86_64) was publicly released.
View 4 Replies View RelatedI am currently running 9.10 ubuntu (gnome). I have a dual core intel chip at 3.00 ghz. My mobo is an ASUS P5ND2-SLI. My mobo will support up to 8gb of ram. Now, as we all know, 32-bit os/kernel will only support like 3.2gb, and 64-bit like 4gb. I'd like to install a pae kernel so I can get the most from my mobo, but honestly, I don't have a clue where to start looking for a pae kernel. I'd like to be able to select it from the list that already appears after the grub loads, and if I like it, be able to remove the rest from the list, or just make it default.
Question, in CPU-G, it says my architecture is i686. I don't know if that's the os/distro, or the kernel itself. it also lists the GCC version as 4.4.1 and Xorg as 1.6.4. my current kernel is Linux 2.6.31-22-generic. Again, I'm trying to find a pae kernel, but I don't know if my os/distro will make a difference, if the architecture is the kernel or os itself. I am still fairly new to ubuntu, and I must say, I've made the switch completely from windows.. which blows...

View 2 Replies View RelatedWhen I run yum list installed command the output shows two kernels:

Would it therefore be safe to remove the first kernel in the installed list to save having two kernels being updated everytime I run yum update? Or is the PAE kernel dependant upon the original?
The shell is bash.
The directory path, /this/is/directory/aa, is actually linked to the path /this/is/link/aa.
So when I cd to the aa directory I am in /this/is/link/aa and there is no /this/is/link/bb hence the error with ls.
My question is how does cd understand relative paths and not return an error the way ls does?
do you have any code to flash led lights with paralel port (device driver programming)or any lecture about this subject .if there is a working code this would be better ofcourse.

purpose of application is to get the content of those arrays and to explain it in descriptive words instead of hex numbers.ofcourse this can be done by file pointers and reading also with out header file inclusion, but as i am working in C, once compiled, those variables are in my address space in i include header file.
