From dedf1c2d17cd81796fc25190fd194e8dd0269817 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 23 Oct 2012 11:40:02 -0400 Subject: [PATCH] Revert "SUNRPC: Ensure we close the socket on EPIPE errors too..." commit b9d2bb2ee537424a7f855e1f93eed44eb9ee0854 upstream. This reverts commit 55420c24a0d4d1fce70ca713f84aa00b6b74a70e. Now that we clear the connected flag when entering TCP_CLOSE_WAIT, the deadlock described in this commit is no longer possible. Instead, the resulting call to xs_tcp_shutdown() can interfere with pending reconnection attempts.
