Subject: Re: [PATCH] mm: disable `vm.max_map_count' sysctl limit

	[resent because I can't type]

> 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.
