Hello,
kernel test robot noticed a -18.0% regression of stress-ng.link.ops_per_sec on:
commit: 8d993618350c86da11cb408ba529c13e83d09527 ("btrfs: migrate get_eb_page_index() and get_eb_offset_in_page() to folios")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
testcase: stress-ng
test machine: 36 threads 1 sockets Intel(R) Core(TM) i9-9980XE CPU @ 3.00GHz (Skylake) with 32G memory
parameters:
nr_threads: 10%
disk: 1SSD
testtime: 60s
fs: btrfs
class: filesystem
test: link
cpufreq_governor: performance
