Subject: [btrfs] ba60dcc6ad: aim7.jobs-per-min 17.2% improvement

Greeting,

FYI, we noticed a 17.2% improvement of aim7.jobs-per-min due to commit:


commit: ba60dcc6ad75409ddb24dbc3524be91ff5673522 ("btrfs: speed up btrfs_get_##bits helpers")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master

in testcase: aim7
on test machine: 72 threads Intel(R) Xeon(R) Gold 6139 CPU @ 2.30GHz with 128G memory
with following parameters:

	disk: 4BRD_12G
	md: RAID0
	fs: btrfs
	test: sync_disk_rw
	load: 20
	cpufreq_governor: performance
	ucode: 0x2000065

test-description: AIM7 is a traditional UNIX system level benchmark suite which is used to test and measure the performance of multiuser system.
test-url: https://sourceforge.net/projects/aimbench/files/aim-suite7/





Details are as below:
