For 5.8 this is a simple backport with one conflict caused by function
md_make_request() renamed to md_submit_bio(). Then it can be easily
cherry picked to 5.4 but will need a change to use
generic_{start,end}_io_acct() instead of disk_{start,end}_io_acct(). I
can send you the backported patches if you wish.-- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1891151 Title: md: improve IO accounting Status in linux package in Ubuntu: Confirmed Status in linux source package in Focal: Confirmed Status in linux source package in Groovy: Confirmed Bug description: [IMPACT] Currently reported IO stats may be incorrect or missing. This adds correct statistics about in-flight IOs and IO processing time, interpreted e.g. in iostat as await, svctm, aqu-sz and %util. [FIX] Commit: 41d2d848 md: improve io stats accounting This isn't a clean cherry pick to either 5.8 or 5.4, so some backport work is necessary.
