![]() default_acl and acl of newly created inode will be initiated as ACL_NOT_CACHED in vfs function inode_init_always() and later will be updated by calling xxx_init_acl() in specific filesystems. However, when default_acl and acl are NULL, then they keep the value of ACL_NOT_CACHED. This patch changes the code to cache NULL for acl / default_acl in this case to save unnecessary ACL lookup in future.
