Parent article: More notes on reiser4
No, the problem is precisely that if a diretory has several parents, you need to make sure nobody messes around with one of the paths while you are screwing up another one. For that you'd have to be able to find all parents and lock them before doing anything... and that will have a heavy cost if done naïvely. Al (and Linus) is asking how do they solve these problems. If the ReiserFS guys have good answers, symlinks (as second-class citizens) could be on the way out. I for one doubt they have the answers (or are able to come up with them). Time will tell.

if it
was considered typical for a directory to have multiple
parent pointers, and there were consistent conventions for
performing atomic locking on all the parents of a directory
at once, there might be no problem.
