This stuff also addressed one problem I forgot to tell you about: During a lookup, you might find an item that is moved to another chain by another cpu, so your lookup is redirected to another chain. You can miss your target. You must find a way to detect such thing to restart the lookup at the beginning (of the right chain). Either you stick the chain number in a new inode field (that costs extra memory), or you use the 'nulls' value that can let you know if you ended your lookup in the right chain. -- 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
