> [PATCH] net: refine {udp|tcp|sctp}_mem limits
>
> Current tcp/udp/sctp global memory limits are not taking into account
> hugepages allocations, and allow 50% of ram to be used by buffers of a
> single protocol [ not counting space used by sockets / inodes ...]
>
> Lets use nr_free_buffer_pages() and allow a default of 1/8 of kernel ram
> per protocol, and a minimum of 128 pages.
> Heavy duty machines sysadmins probably need to tweak limits anyway.
