From f0b6ae56a61d32694f80a0cf49dd160dd85e1fab Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Tue, 9 Mar 2021 00:00:20 -0800 Subject: [PATCH] fs: orangefs: fix error return code of orangefs_revalidate_lookup() [ Upstream commit 4c2b46c824a78fc8190d8eafaaea5a9078fe7479 ] When op_alloc() returns NULL to new_op, no error return code of orangefs_revalidate_lookup() is assigned. To fix this bug, ret is assigned with -ENOMEM in this case. Fixes: 8bb8aefd5afb ("OrangeFS: Change almost all instances of the string PVFS2 to OrangeFS.")
