remove_on_dev_loss module parameter in scsi_transport_fc

Hi All, I saw SLES10 2.6.16.21-0.8-smp kernel supports a new module parameter "remove_on_dev_loss" in scsi_transport_fc. The parameter description is remove_on_dev_loss:Boolean. When the device loss timer fires, this variable controls whether the scsi infrastructure for the target device i

[PATCH] Fix race condition between scsi scan and sdev block/unblock

2006-11-28 Thread Bino . Sebastian
James, Our testing has encountered an error between sdev initialization/ scanning and the sdev block/unblock behavior. What we have seen is that new target detection will kick off a scan, and that an sdev will be in the creation process with the state SDEV_CREATED. At this point a link event oc

So following the previous patch to pass a struct dev pointer to dma_is_consistent() there is still dma_cache_sync left which does not receive a dev pointer. Ralf - Pass struct dev pointer to dma_cache_sync() dma_cache_sync() is ill-designed in that it does not have a struct device
