I think you meant /proc/sys/net/ipv4/udp_{r,w}mem above.
Patch not in-lined making replying more difficult.

I think either the above should be renamed to udp_{r,w}mem_min, or
they should be changed to a 3-tuple like tcp_{r,w}mem, and the code
refactored accordingly (but then what to do about
/proc/sys/net/core/{r,w}mem_max).
