Changes since v1: Fixed some formatting errors to make the patchset less confusing.
A patchset from linux-5.15 should be backported to 4.19 that can significantly improve ext4 fs read and write performance. Unixbench test results for linux-4.19.318 on Phytium D2000 CPU are shown below.
Also, this looks like a performance issue, why not just use a newer kernel (i.e. 5.15.y) to get the benefit of this, and many other, increased performance fixes? 4.19.y is only going to be alive for a few more months, if you haven't already planned to move off of it yet, you need to do so now.
