Subject: [SUNRPC] 3bc6a407d1: fsmark.files_per_sec -12.9% regression

Greeting,

FYI, we noticed a -12.9% regression of fsmark.files_per_sec due to commit:


commit: 3bc6a407d1a090417218ecdb0dd4a92a5d75704b ("[PATCH RFC] SUNRPC: Use zero-copy to perform socket send operations")
url: https://github.com/0day-ci/linux/commits/Chuck-Lever/SUNRPC-Use-zero-copy-to-perform-socket-send-operations/20201110-000351
base: git://git.linux-nfs.org/projects/trondmy/linux-nfs.git linux-next

in testcase: fsmark
on test machine: 192 threads Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:

	iterations: 1x
	nr_threads: 64t
	disk: 1BRD_48G
	fs: xfs
	fs2: nfsv4
	filesize: 4M
	test_size: 40G
	sync_method: fsyncBeforeClose
	cpufreq_governor: performance
	ucode: 0x5003003

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:
