mkinitrd relies on /sys/class/scsi_host/*/proc_name instead of /sys/block/sd*/device/../../../moalias to get the scsi driver module name. As a fallback the sysfs driver name could be used, which does not match the module name either ('storvsc' vs. 'hv_storvsc'). Signed-off-by: Olaf Hering <olaf at aepfle.de> --- drivers/stag...

...trols that target. The objective is to be able to unload and reload the kernel module when the drive gets into a state that requires a SCSI bus reset for recovery. The best I've been able to come up with so far is: SCSIMOD=$(cat /sys/class/scsi_tape/${DEV##*/}/device/../../scsi_host:host*/proc_name) Anyone know of a way that is a bit less convoluted? -- Bob Nichols "NOSPAM" is really part of my email address.

On my C5 machine (a Dell XPS420) I have a 500Gb disk on the internal SATA controller. I also have a SiI3132 dual-port multi-device eSATA card. This is connected to an external SATA array of disks. Now occasionally I see something like this in my logs ata7.01: exception Emask 0x0 SAct 0x0 SErr 0x0 a ction 0x0 ata7.01: irq_stat 0x00060002, device error via D 2H FIS ata7.01: cmd

This series implements virtio-scsi queue steering, which gives performance improvements of up to 50% (measured both with QEMU and tcm_vhost backends). The patches build on top of the new virtio APIs at http://permalink.gmane.org/gmane.linux.kernel.virtualization/18431; the new API simplifies the locking of the virtio-scsi driver nicely, thus it makes sense to require them as a prerequisite.
