| 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. |
