Here's the bug that's tracking them: https://bugzilla.redhat.com/show_bug.cgi?id=811138 The problem seems to be regression introduced by 3114ea7a. An inode field was added to the nfs4_exception struct, but most of the callers of nfs4_handle_exception set it to NULL. Would it be reasonable to push this to stable too? -- Jeff Layton <jlayton@xxxxxxxxxx> -- 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
