Subject: Re: [PATCH] mm: disable `vm.max_map_count' sysctl limit
Date: Mon, 27 Nov 2017 22:46:03 +0300 [thread overview]
Message-ID: <20171127194603.GA28115@avx2> (raw)
> vm.max_map_count
I always thought it is some kind of algorithmic complexity limiter and
kernel memory limiter. VMAs are under SLAB_ACCOUNT nowadays but ->mmap
list stays:
$ chgrep -e 'for.*vma = vma->vm_next' | wc -l
41
In particular readdir on /proc/*/map_files .
I'm saying you can not simply remove this sysctl.
