Ryan Harper 8741f2defa Add virtio-blk support to path_id ... This patch adds a case handling path_id invoked on a virtio-blk device. Currently path_id walks the parent path to virtio-pci but doesn't know that it's the end of the path and exits without building the path (providing no output resulting in no disk/by-path symlinks to virtio-blk devices). This patch handles the virtio-pci path and updates the path accordingly. /lib/udev/path_id --debug /block/vda udev_device_new_from_syspath: device 0x2300120 has devpath '/devices/virtio-pci/virtio1/block/vda' udev_device_new_from_syspath: device 0x2300380 has devpath '/devices/virtio-pci/virtio1' udev_device_new_from_syspath: device 0x2300670 has devpath '/devices/virtio-pci' ID_PATH=virtio-pci-virtio1 And with the current persistent-storage rules generates: % ls -al /dev/disk/by-path | grep vda lrwxrwxrwx. 1 root root 9 Jun 1 22:09 virtio-pci-virtio1 -> ../../vda Signed-off-by: Ryan Harper <ryanh@us.ibm.com>		2010-06-29 17:22:49 +02:00
