Subject: [linus:master] [mm/mmap]  6852c46c78:  stress-ng.spawn.ops_per_sec
 2.9% improvement



Hello,

kernel test robot noticed a 2.9% improvement of stress-ng.spawn.ops_per_sec on:


commit: 6852c46c783d20a4c0153d14d2990040e5e6e47e ("mm/mmap: move vma operations to mm_struct out of the critical section of file mapping lock")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

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

	nr_threads: 100%
	disk: 1HDD
	testtime: 60s
	class: exec_spawn
	test: spawn
	cpufreq_governor: performance


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