I am not intending to frustrate you. :) My unanswered questions are based on the idea that the two switches to vmst= at produce hundreds of different data points: vmstat -z | wc -l 274 vmstat -z | wc -l 218 This is a lot of data (492 points) to check for changes. Naturally, I'd lik= e to reduce this check (which obviously has to be scripted) to data which is relevant.=20 With that, would you be so kind as to answer the following question? Are you asking me to check each and every entry for each switch -m and -z to vmstat to see what is growing OR is it possible to reduce the number of data points to a specific useful subset?=20 Thank you for your patience, as I am not a (modern) kernel dev. --=20 You are receiving this mail because: You are the assignee for the bug.=
