Hello,

kernel test robot noticed a 21.4% improvement of stress-ng.mmapmany.ops_per_sec on:


commit: 17983dc617837a588a52848ab4034d8efa6c1fa6 ("maple_tree: refine mas_preallocate() node calculations")
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: 10%
	disk: 1HDD
	testtime: 60s
	fs: ext4
	class: vm
	test: mmapmany
	cpufreq_governor: performance


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