...ts around VBD back driver. This function is also useful to implement the I/O resource management mechanism. The series of patch enables you to get the statistical information of VBD behavior through /proc/xen/vbd and display the information by xentop. I appreciate any comments.

...ot. In because that -xen0 kernel is upload many modules, then above functions is handled. But, In -xenU kernel, not. This patch is to update totalram_pages at also init function. However, If it is correct that current_pages is equal to totalram_pages, should it unify these variables?

...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 working on the CFQ scheduler use this functionality to control asynchronous I/Os with a little enhancement. You have to apply the patch dm-ioband v1.0.0 before applying this series of patches, which can be found at: http://people.valinux.co.jp/~ryov/dm-ioband And you have to select the...
