Greeting,
FYI, we noticed a 12.8% improvement of netperf.Throughput_tps due to commit:
commit: 2463a604a86728777ce4284214a52de46a808c9e ("[PATCH v3 2/3] Introduce enums for the SAM, message, host and driver status codes")
url: https://github.com/0day-ci/linux/commits/Bart-Van-Assche/Introduce-enums-for-SCSI-status-codes/20210524-105751
base: https://git.kernel.org/cgit/linux/kernel/git/mkp/scsi.git for-next
in testcase: netperf
on test machine: 192 threads 4 sockets Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:
ip: ipv4
runtime: 300s
nr_threads: 16
cluster: cs-localhost
test: TCP_CRR
cpufreq_governor: performance

The above email reports a performance improvement for the networking
subsystem while my patch only affects the SCSI subsystem and should not
have any performance impact. I'm confused by the above feedback ...

I suspect it related with cache alignment, 2463a604a8 changes "u8"
(size:1) to "enum xxx_status" (size: 4), the cache alignment is better
than before , so cause the improvement.
