+Subject: fuse: Propagate dentry down to inode_change_ok()
+Origin: https://git.kernel.org/linus/62490330769c1ce5dcba3f1f3e8f4005e9b797e6
+
+To avoid clearing of capabilities or security related extended
+attributes too early, inode_change_ok() will need to take dentry instead
+of inode. Propagate it down to fuse_do_setattr().
