From 11c870c0b532feaf740f2cb2c6b8a1d7970b0da4 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 31 May 2022 11:03:06 -0400 Subject: [PATCH] pNFS: Don't keep retrying if the server replied NFS4ERR_LAYOUTUNAVAILABLE [ Upstream commit fe44fb23d6ccde4c914c44ef74ab8d9d9ba02bea ] If the server tells us that a pNFS layout is not available for a specific file, then we should not keep pounding it with further layoutget requests.
