Subject: [linus:master] [btrfs]  ad21f15b0f:  fio.write_iops -40.1% regression



Hello,

kernel test robot noticed a -40.1% regression of fio.write_iops on:


commit: ad21f15b0f795daf8723dddbcb61797d4f1c2aed ("btrfs: switch to the new mount API")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

testcase: fio-basic
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:

	runtime: 300s
	disk: 1HDD
	fs: btrfs
	nr_task: 1
	test_size: 128G
	rw: write
	bs: 4k
	ioengine: falloc
	cpufreq_governor: performance


In addition to that, the commit also has significant impact on the following tests:
