It's not possible with the current API to do it through open syscall. Another possibility is to look at /proc/locks. But I think we really need O_DELETE flag that will force a file to be removed on close - we will be able to do O_DENYDELETE checks atomically. -- Best regards, Pavel Shilovsky. -- 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
