[Kernel-packages] [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.

This isn't a clean cherry pick to either 5.8 or 5.4, so some backport
work is necessary.
