Subject: Re: [REGRESSION] ioprio performance hangs, bisected

Would fix/revert reach 6.13-rc1? I think this regression has
significant nagative impact on daily usage. From time to time,
my system would *stuck* for seconds, sometimes even when
just `cat` some small file it would take seconds, and once,
my desktop failed to resume from a suspend, I had to power cycle the system;
Polling /proc/diskstats, I noticed Block-IO read latency,
delta(# of milliseconds spent reading)/delta(# of reads completed),
is very high, ~200ms average, and frequently reaches 10s.
(Strangely block-io write latency seems normal.)
My bisect also land on this commit, revert or apply this patch would
fix it.
Kind of think that 6.13-rc1 would be very unpleseant to use without
a fix/revert for this.
David
