From 3b32dda29f994f036de528c07221fa72ba721f1c Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 7 Apr 2022 09:50:19 -0400 Subject: SUNRPC: Handle low memory situations in call_status() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit 9d82819d5b065348ce623f196bf601028e22ed00 ] We need to handle ENFILE, ENOBUFS, and ENOMEM, because xprt_wake_pending_tasks() can be called with any one of these due to socket creation failures.
