Hello,

kernel test robot noticed a -98.5% regression of filebench.sum_operations/s on:


commit: 7de1bab7712daba2c9bb28e60a3e14aa980c7e7b ("cifs: Cut over to using netfslib")
https://git.kernel.org/cgit/linux/kernel/git/dhowells/linux-fs.git cifs-netfs

testcase: filebench
test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz (Ice Lake) with 128G memory
parameters:

	disk: 1HDD
	fs: ext4
	fs2: cifs
	test: randomwrite.f
	cpufreq_governor: performance


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