Subject: [btrfs]  59c7b566a3:  fsmark.files_per_sec 2.3% improvement



Greeting,

FYI, we noticed a 2.3% improvement of fsmark.files_per_sec due to commit:


commit: 59c7b566a3b653fe7865cef007c053fd88de8317 ("btrfs: index free space entries on size")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

in testcase: fsmark
on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz with 128G memory
with following parameters:

	iterations: 1x
	nr_threads: 1t
	disk: 1HDD
	fs: btrfs
	filesize: 4K
	test_size: 80M
	sync_method: fsyncBeforeClose
	nr_files_per_directory: 1fpd
	cpufreq_governor: performance
	ucode: 0xd000280

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:

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.
