Antgroup is using 5.10.y in product environment, we found several patches are missing in 5.10.y tree. These patches are needed for us. So we backported them to 5.10.y. Also backport to 5.15.y and 6.1.y to prevent regression.

commit ccc031e26afe60d2a5a3d93dabd9c978210825fb upstream.
[backport for 6.1.y]
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.
