The 'disable_cb' callback is designed as an optimization to tell the host we don't need callbacks now. As it is not reliable, the debug check is overzealous: it can happen on two CPUs at the same time. Document this. Even if it were reliable, the virtio_net driver doesn't disable callbacks on transmit so the START_USE/END_USE debugging reentrance protection can be easily tripped

The 'disable_cb' is really just a hint and as such, it's possible for more work to get queued up while callbacks are disabled. Under stress with an SMP guest, this printk triggers very frequently. There is no race here, this is how things are designed to work so let's just remove the printk. Signed-off-by: Anthony Liguori <aliguori at us.ibm.com> Acked-by: Rusty Russell

When transferring DMA ownership back to the CPU there should never be any writeback from the cache, as the buffer was owned by the device until now. Instead it should just be invalidated for the mapping directions where the device could have written data. Note that the changes rely on the fact that kmap_atomic is stubbed out for the !HIGHMEM case to simplify the code a bit. Signed-off-by:

I'm using Wine 0.9.11~winehq1-1 on Debian Sid. I've been trying to install IE6 and MS Office 2000 for the last few days. As a side note, the only way I managed to install IE6 was through Sidenet. No luck with any other method (reg files, winetools...) Office 2000 installs, but when I try to run the program it says: warn:module:load_dll Failed to load module

Wine seems to be trying to run MS programs. 'wine /windows/Programs/access/office/msaccess.exe' starts 'access'.

Hello all, If you're successfully running MS Word on Wine, could you please tell me what version of Wine you're using? Also, did you use Winetools for your setup or did you do it "from scratch"? I was not able to run Word properly with recent Wine versions. When I try to save a file, I get some message like "... Would you like to repair this application now?", after

Hi Matthijs, Changing PromoteCastOfAllocation to not replace aggregate allocas with non-aggregate allocas if they have GEP users sounds reasonable to me. Finding the maximum alignment is sometimes still useful though, so it would be nice to update the alignment field of the alloca even if its type is left unchanged.

Hi, We?re migrating to a Cpanel hosting system. Our passwords are currently stored in MD5. I looked at the post login scripting to be able to start storing the plain text passwords as people login temporarily so we can automate our migration. It seems that the password is not available in the post login environment variables. Is there any way we can get access to the plain text password upon

I am trying to compile Samba 2.2.4 on an HP-UX 10.20 machine, and I get this error at the end: checking configure summary... ERROR: No locking available. Running Samba would be unsafe configure: error: summary failure. Aborting config I looked on the web for possible causes, I didn't see anything that answered my question. This box that I'm compiling on is currently running 1.9.16, and

Starting html help in the current version of R has a very annoying side-effect. It indiscriminantly removes $HOME/.R, and replaces it with a virgin copy. I discovered that when all of a sudden I got complaints about my startup "library" not being found. Below is a modified version of the script that doesn't do this. It is not perfect yet (it shouldn't try to recreate links

This is a MS Access problem I dont see in other posts. I have wine up and running and I now have it working with one other app, a spice cad program called scad3.exe. When I run it via wine I do get error messages, but since the program comes up and works fine any way I have been ignoring those errors. But I will list them here anyway, in case some expert can tell if they are relevant to my

Hello again, I was testing today's SNAP (openssh-SNAP-20000830.tar.gz) in my Solaris 2.6-8 environment, when I found some problems with the ssh2 support. While connecting, it seeds the RNG something like 32 times! And then once connected, it seeds again 2 or 3 times with *every* keystroke! This makes for some slow going. This happens on all of the Solaris boxes I tried. Binary was

This is really strange. The samba server in question is a domain member server on a Windows NT 4.0 Domain network. It runs Gentoo 2004.3 with a 2.4.24 kernel. The Gentoo server was upgraded from Samba 3.0.5 to 3.0.8 last night. After the upgrade, the server had to be re-joined to the domain. After that, everything appeared to be working. This morning we found that the MSAccess database files

Hello, I know this is off topic, but I've come to the conclusion that the only people who can answer my question is other Samba users... I would like to deploy on our network a centrally administered antivirus program. We're running Win98 machines doing NT type logins to Samba running on a RedHat 6.1 box. It seems that as I have researched antivirus programs which can be centrally
