v2.6.34-rc2~48 got 8eae939f net: add limit for socket backlog
This adds sk_add_backlog_limitted() which makes the backlog
have a size, and therefore adding an skb to the backlog can
fail, a later patch changed all non-limitted calls to use the
limitted caller via a3a858ff. The older kernels don't have a
size and as such always are successfull when adding to the
backlog.
