| |
Hi, The LTP test fcntl23 is failing. It does, in essence, fd = open(xxx, O_RDWR|O_CREAT, 0777); if (fcntl(fd, F_SETLEASE, F_RDLCK) == -1) fail; fcntl always returns EAGAIN here. The manual page says that a read lease causes notification when `another process' opens the file for writing or truncates it. The kernel implements `any process' (including the current one).
Which semantics are correct? Personally I think that what the kernel implements is correct (you can't get a read lease unsless there are no writers _at_ _all_)
