Subject: [linus:master] [btrfs] 5e85262e54: stress-ng.fallocate.ops_per_sec
40.7% regression
Hello,
kernel test robot noticed a 40.7% regression of stress-ng.fallocate.ops_per_sec on:
commit: 5e85262e542d6da8898bb8563a724ad98f6fc936 ("btrfs: fix fsync of files with no hard links not persisting deletion")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[still regression on linus/master 4cb6c8af8591135ec000fbe4bb474139ceec595d]
[still regression on linux-next/master 3a83b350b5be4b4f6bd895eecf9a92080200ee5d]
testcase: stress-ng
config: x86_64-rhel-9.4
compiler: gcc-12
test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz (Ice Lake) with 128G memory
parameters:
nr_threads: 100%
disk: 1HDD
testtime: 60s
fs: btrfs
test: fallocate
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
