From 48e49187753ec3b4fa84a7165c9b7a59f3875b56 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 19 Dec 2005 17:11:22 -0500 Subject: [PATCH] SUNRPC: Fix "EPIPE" error on mount of rpcsec_gss-protected partitions gss_create_upcall() should not error just because rpc.gssd closed the pipe on its end. Instead, it should requeue the pending requests and then retry.
