Subject: [NFSD] c6138abff4: fsmark.files_per_sec -6.5% regression
Greeting,
FYI, we noticed a -6.5% regression of fsmark.files_per_sec due to commit:
commit: c6138abff45e497e14575b6ac321b17899a5944c ("[PATCH v2 1/1] NFSD: sleeping function called from invalid context at kernel/locking/rwsem.c")
url: https://github.com/intel-lab-lkp/linux/commits/Dai-Ngo/NFSD-sleeping-function-called-from-invalid-context-at-kernel-locking-rwsem-c/20220521-045428
base: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git 3b5e1590a26713a8c76896f0f1b99f52ec24e72f
patch link: https://lore.kernel.org/linux-nfs/1653079929-18283-1-git-send-email-dai.ngo@oracle.com
in testcase: fsmark
on test machine: 144 threads 4 sockets Intel(R) Xeon(R) Gold 5318H CPU @ 2.50GHz with 128G memory
with following parameters:
iterations: 1x
disk: 1SSD
nr_threads: 6t
fs: xfs
filesize: 8K
test_size: 60G
sync_method: NoSync
cpufreq_governor: performance
ucode: 0x7002402
fs2: nfsv4
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/
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <oliver.sang@...el.com>
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
sudo bin/lkp install job.yaml # job file is attached in this email
bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
sudo bin/lkp run generated-yaml-file
# if come across any failure that blocks the test,
# please remove ~/.lkp and /lkp dir to run from a clean state.
