In commit ba7438aed924 ("vhost: don't bother copying iovecs in handle_rx(), kill memcpy_toiovecend()"), we advance iov iter fixup sizeof(struct virtio_net_hdr) bytes and fill the number of buffers after doing the socket recvmsg(). This work well but was broken after commit 6e03f896b52c ("Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net") which tries to advance

Hey folks, I'm experiencing some weird errors all of a sudden. I have not made any changes to the config but for some reason I cannot create files/directories on my network share. An example would be the error I get when I try to update the virus signatures on my portable ClamWin install: ERROR: Can't open ..\..\..\Data\log\ClamScanLog.txt in append mode (check permissions!). ERROR:

Provide a splice_read stub for ocfs2. This emits trace lines and does an atime lock/update before calling filemap_splice_read(). Splicing from direct I/O is handled by the caller. A couple of new tracepoints are added for this purpose. Signed-off-by: David Howells <dhowells at redhat.com> cc: Christoph Hellwig <hch at lst.de> cc: Al Viro <viro at zeniv.linux.org.uk> cc: Jens

Hi folks, [I am resending to fix the broken thread in the previous one.] This patchset adds vhost-blk support. vhost-blk is a in kernel virito-blk device accelerator. Compared to userspace virtio-blk implementation, vhost-blk gives about 5% to 15% performance improvement.
