Hey Rusty, This is the way I did the split; patches 1..7 are preparation for multiple ports. Patch 8 adds multiport support. It's the big one since we have to put the header in and retain support for multiple consoles and console resizing. Patch 9 adds port hotplug Patch 10 adds sysfs entries and 12 adds debugfs. Patches 13, 14 and 15 add throttling, caching and unplug features.

Hello all, Here is a new iteration of the patch series that implements a transport for guest and host communications. I've tested for compatibility (old qemu & new kernel, new qemu & old kernel, new qemu & new kernel) and it all works fine. To maintain backward compatibility, the first port to be spawned (port at id 0) is to be a console port, to be bound to hvc. This keeps new

Hi all, With this series of patches, you can determine the owners of any type of I/Os. I ported the previous version to linux-2.6.26-rc2-mm1. This makes dm-ioband -- I/O bandwidth controller -- be able to control the Block I/O bandwidths even when it accepts delayed write requests. Dm-ioband can find the owner cgroup of each request. It is also possible that OpenVz team and NEC Uchida-san team

Hey Rusty, These updated patches in the series return -EFAULT on copy_xx_user errors and also move the copy_from_user into fops_write() instead of it being in send_buf. This enables send_buf to just read from kernel buffers, making it simpler. This also allows write()s to write more to the host in one go, removingthe 4k limitation. I do limit the writes to 32k at once to not put too much
