hi, All,
we don't have enough knowledge to understand fully the discussion for this
patch, we saw "NACK" but there were more discussions later.
so below report is just FYI what we observed in our tests. thanks
Thanks for the report. It was nack'ed because of the change to
smaps/maps files in proc.
Hello,
kernel test robot noticed a 858.5% improvement of vm-scalability.throughput on:

patch subject: [PATCH] /dev/zero: make private mapping full anonymous mapping
testcase: vm-scalability
config: x86_64-rhel-9.4
compiler: gcc-12
test machine: 224 threads 4 sockets Intel(R) Xeon(R) Platinum 8380H CPU @ 2.90GHz (Cooper Lake) with 192G memory
parameters:
runtime: 300s
test: small-allocs
It seems this benchmark allocates huge amount of small areas (each area
is as big as 40K) by mmap'ing /dev/zero.
This patch makes /dev/zero mapping a full anonymous mapping, so the
later vma_link_file() is actually skipped, which needs acquire file rmap
lock then insert the mapping into file rmap tree. The below profiling
also showed this.
Quoted here so that we don't have to scroll down:

94.55 -93.1 1.40 ± 51% perf-profile.children.cycles-pp.ksys_mmap_pgoff
94.25 -93.0 1.30 ± 59% perf-profile.children.cycles-pp.__mmap_region
92.91 -92.9 0.00 perf-profile.children.cycles-pp.osq_lock
94.45 -92.7 1.72 ± 34% perf-profile.children.cycles-pp.do_mmap
94.46 -92.6 1.83 ± 31% perf-profile.children.cycles-pp.vm_mmap_pgoff
It significantly speed up mmap for this benchmark and the rmap lock
contention is reduced significantly for both multi-processes and
multi-threads.
The benchmark itself may exaggerate the improvement, but it may really
speed up some real life workloads. For example, multiple applications
which may allocate anonymous mapping by mmap'ing /dev/zero, then they
may have contention on /dev/zero's rmap lock.
It doesn't make too much sense to link /dev/zero anonymous vmas to the
file rmap tree. So the below patch should be able to speed up the
benchmark too.
Oliver, can you please give this patch a try?

Because /dev/zero's private mapping is an anonymous mapping with valid
vm_file, so we need to bail out early if the vma is anonymous even
though it has vm_file. IMHO, making /dev/zero private mapping a full
anonymous mapping looks more clean.
