I think it's a requirement; without it: - if we set the flag that allows the client to turn off sillyrename, then users will see a regression (ESTALE after clean shutdowns in situations we previously guaranteed safe). - if we don't set that flag, we don't get to turn off client sillyrename. The only improvement is that we avoid ESTALE after crashes on files unlinked by a different client than held it open. I don't think that's very interesting on its own. --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
