Hello,
when reviewing this report internally, we cannot connect the regression with
changes. however, we saw similar regression on different stress-ng tests and
the data is quite stable (comparing to the regression level), so we still
report what we observed in our tests just FYI.
below are details.
kernel test robot noticed a -42.3% regression of stress-ng.utime.ops_per_sec on:
commit: 8a4fd33d879fb303b207f06ea6340d73f698c4ed ("jbd2: remove unused 'JBD2_CHECKPOINT_IO_ERROR' and 'j_atomic_flags'")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: stress-ng
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:
nr_threads: 10%
disk: 1HDD
testtime: 60s
fs: ext4
class: os
test: utime
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
