From ccc031e26afe60d2a5a3d93dabd9c978210825fb Mon Sep 17 00:00:00 2001 From: Jiachen Zhang Date: Wed, 28 Sep 2022 20:19:34 +0800 Subject: fuse: always revalidate rename target dentry The previous commit df8629af2934 ("fuse: always revalidate if exclusive create") ensures that the dentries are revalidated on O_EXCL creates. This commit complements it by also performing revalidation for rename target dentries. Otherwise, a rename target file that only exists in kernel dentry cache but not in the filesystem will result in EEXIST if RENAME_NOREPLACE flag is used.
