These patches address issues in the kernel part of xenoprof: * Ill-advised use of on_each_cpu() can lead to sleep with interrupts disabled. * Race conditions in active_domains code. * Cleanup of active_domains code. Comments welcome. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hello, This is a new iteration of the patches that implement virtio-serial. Changes include: * Adding support for port hot-add * Creating ports at specific ids that can be bound to specific apps / usage * Cleanups This code still doesn't get rid of the support for assigning names to ports but it just has to be ripped out. Comments welcome. Thanks, Amit.

Hi, below comes a new version of the series of patches implementing quota support for ocfs2-tools. I've fixed the calls of ocfs2_malloc_blocks() which were given number of bytes instead of number of blocks. Besides that the series should be the same. Honza

Hello, Here are two patches. One implements a virtio-serial device in qemu and the other is the driver for a guest kernel. While working on a vmchannel interface that is needed for communication between guest userspace and host userspace, I saw that most of the interface can be abstracted out as a "serial" device with "ports". Some requirements for a vmchannel are listed at

Hello all, This are the latest version of the patches. Lots of things have changed since the last submission. A few of which I remember: - VNC copy / paste works* (* conditions apply) - client vnc copies get propagated to guest port 3 (/dev/vmch3) - guest writes to port 3 (/dev/vmch3) go straight to client's clipboard - sysfs hooks to autodiscover ports - support for 64 ports in this

Hi, I'm sending a series of patches implementing quota support into ocfs2-tools. It's the same as the original huge patch I've sent but now it's split as Joel asked. I've also realized that when disabling SPARSE feature, we should update quota information. That piece of code is missing, I'll implement it soon. Comments welcome. Honza

Hi, this is the next version of quota support for quota tools. I've addressed all the comments of Tao, Joel and others. Sparse feature disabling also correctly updates quota information now and the patch is merged into the tunefs support patch. Honza

Hello all, Here is a new iteration of the patch series that implements a transport for guest and host communications. The code has been updated to reuse the virtio-console device instead of creating a new virtio-serial device. I've tested for compatibility (old qemu & new kernel, new qemu & old kernel, new qemu & new kernel) and it all works fine. There are a few items on my

Hi, This is the second batch of Ocfs2 patches intended for the merge window. The 1st batch were sent out previously: http://lkml.org/lkml/2008/12/19/280 The bulk of this set is comprised of Jan Kara's patches to add quota support to Ocfs2. Many of the quota patches are to generic code, which I carried to make merging of the Ocfs2 support easier. All of the non-ocfs2 patches should have

If someone passes in an address with a scopeid then we end up overwriting the entire address string.

I've been seeing the Dovecot/SSL/Fedora 1 problem.

Hello, This is the patch that I have for adding support for multiple ports to virtio_console. It's pretty stable in my testing so far and the memory corruption that I had earlier has been resolved in linux-next so I'm proposing this for inclusion. This currently uses device major number 60 from the experimental range; Alan could you please reserve a new major number for virtio_console?
