Subject: [scsi] d4ea3041f3: fsmark.files_per_sec -11.8% regression
Greeting,
FYI, we noticed a -11.8% regression of fsmark.files_per_sec due to commit:
commit: d4ea3041f3fd005c1be676f66031c24d06c9dc9b ("scsi: sd: register request queue after sd_revalidate_disk is done")
https://github.com/0day-ci/linux/commits/Ming-Lei/scsi-support-bypass-device-busy-check-for-some-high-end-HBA-with-SSD/20200119-151701
in testcase: fsmark
on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 256G memory
with following parameters:
iterations: 1x
nr_threads: 32t
disk: 1SSD
fs: xfs
filesize: 9B
test_size: 400M
sync_method: fsyncBeforeClose
nr_directories: 16d
nr_files_per_directory: 256fpd
cpufreq_governor: performance
ucode: 0x500002c
test-description: The fsmark is a file system benchmark to test synchronous write workloads, for example, mail servers workload.
test-url: https://sourceforge.net/projects/fsmark/
In addition to that, the commit also has significant impact on the following tests:
