From 3c961afed4d4e766b66092e7af8c8e8005053505 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Thu, 10 May 2012 01:50:01 +0000 Subject: [PATCH] tcp: Schedule rmem for rcvq repair send As noted by Eric, no checks are performed on the data size we're putting in the read queue during repair. Thus, validate the given data size with the common rmem management routine. Signed-off-by: Pavel Emelyanov Acked-by: Eric Dumazet Signed-off-by: David S.
