Hash lockowners on just the owner string rather than on (owner, inode). This makes the owner-string lookup needed for RELEASE_LOCKOWNER simpler (currently it's doing at a linear search through the entire hash table!). That may come at the expense of making (owner, inode) lookups more expensive if a client reuses the same lockowner across multiple files. We might add a separate lookup for that. Signed-off-by: J.
