Hi Linus, Here are a set of miscellaneous small fixes to the afs filesystem including: (1) Fix the afs_server_list struct to be cleaned up with RCU. (2) Fix afs to translate a no-data result from a DNS lookup into ENOENT, not EDESTADDRREQ for consistency with OpenAFS. (3) Fix afs to translate a negative DNS lookup result into ENOENT rather than EDESTADDRREQ. (4) Fix file locking on R/O volumes to operate in local mode as the server doesn't handle exclusive locks on such files. (5) Set SB_RDONLY on superblocks for RO and Backup volumes so that the VFS can see that they're read only. Btw, I did want to ask about (5): Does a superblock being marked SB_RDONLY imply immutability to the application? A 'read only' AFS volume is a snapshot of a writable volume and can be updated. It's only read-only in the sense you can't perform normal filesystem modification ops on it.
