Hi, This patch set fixes two bugs of splice_write in the virtio-console driver. [BUG1] Although pipe->nrbufs is empty, the driver tries to do splice_write. => This induces oops in sg_init_table(). [BUG2] No lock for competition of splice_write. => This induces oops in splice_from_pipe_feed() by bug of any user application. These reports are written in each

I can't find documentation for ->sendpage(). Is the idea that you get a struct page for the payload and can do zero-copy tx? (And can userspace still write to the page, invalidating checksums in the header?) Stefan

Is sendpage or some other alphanumeric paging program available from one of the repos for CentOS 5? I've checked rpmforge and epel. I just wanted to check to see if it might be available somewhere else before I resort to building from source. -- Bowie

We're currently support two paths from VFS to preallocate unwritten extents(from FS_IOC_RESVSP, or fallocate()), likewise, behavior of punching-hole should be treated as the same, this patch tries to teach file_ioctl() to handle FS_IOC_UNRESVSP, underlying filesystem like ocfs2 is wise enough to do the rest of work;-) Signed-off-by: Tristan Ye <tristan.ye at oracle.com> --- fs/ioctl.c

Hi everyone, The Linux Coda drivers and the ext3 patches don't seem to get along very well, at least in Linux 2.4.7. I've got a stock 2.4.7 kernel with a patch applied to the USB drivers (for a sony digital camera; see http://www.sujal.net/tech/linux/ just a change in unusual_devs.h). After I applied the ext3 patches from http://www.uow.edu.au/~andrewm/linux/ext3/ . Basically,

Hello, I see a reproducable panic when doing ibping and aborting it with ^C. My setup is two machines with Mellanox Infinihost III HCAs (one Linux one FreeBSD) connected back-to-back. Details below. I can upload 2 crash dumps, if this is useful. For some reason the port doesn't become ACTIVE, so no packets arrive, but that is probably unrelated. % uname -a FreeBSD cosel.inf.tu-dresden.de

Hello everyone, once again. We are running into a problem, which has shown now 2 times, possible 3 (once the systems looked different.) The environment is 6 HP DL360/380 g5 servers with eth0 being the public interface, eth1 and bond0 (eth2 and eth3) used for clusterware and bond0 also used for OCFS2. The bond0 interface is in active/passive mode. There are no network errors counters showing and

Hi, I've just hit this BUG at drivers/block/virtio_blk.c when updated to the kernel from the top of the Linus git tree. commit a7ca10f263d7e673c74d8e0946d6b9993405cc9c This is my virtual machine running on RHEL7 guest qemu-kvm-1.5.3-60.el7.x86_64 The last upstream kernel (3.17.0-rc4) worked well. I'll try to bisect, but meanwhile this is a backtrace I got very early in the boot. The

Now that ->sendpage() has been removed, MSG_SENDPAGE_NOTLAST can be cleaned up. Things were converted to use MSG_MORE instead, but the protocol sendpage stubs still convert MSG_SENDPAGE_NOTLAST to MSG_MORE, which is now unnecessary.
