From a2fa3ccd7b43665fe14cb562761a6c3d26a1d13f Mon Sep 17 00:00:00 2001 From: Michael Cree Date: Sun, 19 Aug 2012 14:40:56 +1200 Subject: [PATCH] alpha: Don't export SOCK_NONBLOCK to user space. Currently we export SOCK_NONBLOCK to user space but that conflicts with the definition from glibc leading to compilation errors in user programs (e.g. see Debian bug #658460). The generic socket.h restricts the definition of SOCK_NONBLOCK to the kernel, as does the MIPS specific socket.h, so let's do the same on Alpha.
