From 8006daff5f94b157ab1df7c6eb1b55fc470d0d24 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Tue, 7 Sep 2021 13:54:34 -0400 Subject: [PATCH] ceph: don't use -ESTALE as special return code in try_get_cap_refs In some cases, we may want to return -ESTALE if it ends up that we're dealing with an inode that no longer exists. Switch to using -EUCLEAN as the "special" error return.
