From 7945cc6464a4db0caf6dfacdfe05806051c4cb7b Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 5 Jan 2009 00:59:00 -0800 Subject: [PATCH] tcp: Kill extraneous SPLICE_F_NONBLOCK checks. In splice TCP receive, the SPLICE_F_NONBLOCK flag is used to compute the "timeo" value. So checking it again inside of the main receive loop to trigger -EAGAIN processing is entirely unnecessary. Noticed by Jarek P. and Lennert Buytenhek. Signed-off-by: David S.
