From 9bfffea3524b49d0268d01f8e7967f06c4d0a942 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 16 Dec 2020 14:01:07 -0500 Subject: [PATCH] pNFS/flexfiles: Avoid spurious layout returns in ff_layout_choose_ds_for_read The callers of ff_layout_choose_ds_for_read() should decide whether or not they want to return the layout on error. Sometimes, we may just want to retry from the beginning.
