From 95506588d2c1d72ca29adef8ae9bf771bcfb4ced Mon Sep 17 00:00:00 2001 From: Slavomir Kaslev Date: Fri, 16 Nov 2018 11:27:53 +0200 Subject: [PATCH] socket: do a generic_file_splice_read when proto_ops has no splice_read splice(2) fails with -EINVAL when called reading on a socket with no splice_read set in its proto_ops (such as vsock sockets). Switch this to fallbacks to a generic_file_splice_read instead. Signed-off-by: Slavomir Kaslev Signed-off-by: David S.
