Marc and I have an updated version of this at: git://linux-nfs.org/~bfields/linux.git (See the server-cluster-locking-api branch.) Changes include: - bugfixes for GFS2; thanks to some setup help from Wendy Chang and others, Marc has been able to run locking tests against an nfs-exported GFS2 filesystem - preallocation of storage for conflicting lock in lockd's testlock implementation, to avoid a race identified by Trond - Cleanup suggested by Christoph and others, including: - creation of posix-to-flock helper functions - rewrite of posix_test_lock interface to agree with ->lock( ,F_GETLK, ) - removal of some unnecessary parentheses, untangling of some slightly tortured logic We're hoping to get a detailed review from Trond sometime in the coming month, after which we'll probably mailbomb linux-fsdevel again, but any comments are welcome in the meantime. --b. - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
