Hi I am struggling with the correct code syntax to generate xyplots that are different from the default graphics option. This is simplified version of my data: site size dnaconc prey A 44 22.6 1 A 47 18.2 1 B 38 25.6 0 B 47 20.5 1 C 45 30.5 0 C 32 18.5 0 D 45 15.0 1 D 22 20.1 0 So I am using xyplot(dnaconc~size|site,data=bug,groups=prey) to generate 4 panels (one for each site). My

...made over Linus tree and also apply over mst tree's vhost branch. The patches fix an issue where management operations like LUN mapping/unmapping and device addition hang for 30 seconds or up to N minutes depending on the device. The problem is that we use a global mutex to protect the list of tpgs but we hold that mutex during those management operations. So if you are just trying to add another device, it will have to wait on another device if we are in the middle of clearing it's endpoint and it's waiting on hung IO. This patchset fixes up the ordering of how we flush IO and relea...

...e can leave the tpg->vhost_scsi pointer set and we can end up trying to access a freed struct. 3. Management operations like LUN mapping/unmapping and device addition hang for 30 seconds or up to N minutes depending on the device. The problem is that we use a global mutex to protect the list of tpgs and for accessing the tpg, and to make sure they are flushed. We then hold that mutex during a lot of management operations. So if you are just trying to add another device, it will have to wait on another device if we are in the middle of clearing it's endpoint and it's waiting on hung IO....
