The Groovy version is already on the ml, looking at the Focal version
now but s/disk_{start,end}_io_acct/generic_{start,end}_io_acct/g is not
enough.

[Bug 1891151] Re: md: improve IO accounting
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.

Not cleanly cherry picked back to 5.8 or 5.4, so I'm going to push this to the kernel team to investigate. ** Description changed: + [IMPACT] Currently reported IO stats may be incorrect or missing.
