This is another attempt at a posix locking interface that allows us to provide NFS clients with cluster-coherent locking without blocking lockd while the filesystem goes off and talks to other nodes. This time we're using the existing file ->lock operation instead of defining a new export operation for the purpose, and factoring out the code that switches between calling ->lock or the default local operation, so that lock managers and local callers go through the same code. I find the existing interfaces a little odd, and while I think I managed to combine them correctly, I'd certainly appreciate any review. The gfs2 implementation in the last patch is (unfortunately) still just a rough draft that needs some more thought and some testing. --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
