From 482678dc34731c07c64b03fbc44f4c149154b943 Mon Sep 17 00:00:00 2001 From: Hendrik Brueckner Date: Tue, 21 Apr 2009 06:04:22 +0000 Subject: [PATCH] af_iucv: Reject incoming msgs if RECV_SHUTDOWN is set Reject incoming iucv messages if the receive direction has been shut down. It avoids that the queue of outstanding messages increases and exceeds the message limit of the iucv communication path.
