X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~15972^2~56 X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/success//%22http:/www.example.com/cgi/success/?a=commitdiff_plain;h=7218286f5211e3b89a0dea3d368d66d02fd4ef4f;p=xen.git Block device write-verify test. This test imports a ram disk device as a physical device into a domU. The domU initialises the ram disk with data from /dev/urandom and calculates the md5 checksum of the data (using tee as it is written so as to avoid reading it back from the device which might potentially mask problems). The domU is stopped and the md5 checksum of the data on the device is calculated by dom0. The test succeeds if the checksums match, indicating that all the data written by domU was sucessfully committed to the device. This patch also enables tee in BusyBox on the ramdisk and increments the xm-test version number to 0.8.0. The patch also installs the block-integrity tests in the default test set so they get executed.
