| |
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 may result in an EEXIST.
