The entry in question is the vmstat's "InUse" statistics regarding the memorytype "devbuf". It's value seems to consistently increase itself by about 140k over a period of 10 seconds (while the system is doing a buildworld) and has at the time of writing reached a value of 75082k and rising. I do not know If this is alarming or not but i felt i should at least mention it. With kind regards, Pascal Hofstee
