Nfsd must not call forget_cached_acl, that's the filesystems job. I think the right fix is to make sure nfsd4_set_nfs4_acl calls ->set_acl with a NULL ACL structure if there are no entries. Btw, it would be really good if we kept tests like this as a regression test suite. Is there one for NFS already? If not we could add nfs-specific tests to xfstests as well. -- 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
