IMO, for 2.6 FUTEX_FD should be removed or disabled. It doesn't work reliably. As for later, and which extensions to add, Ingo and I discussed this quite a bit already. One of the problems is that once you extend the basic set of operations the possible way are very numerous and the interfaces can explode in number. My hopes are that we can come up with some nice and generally useful additions in the not too distant future and that they can be added to the 2.6 kernel. IMO we cannot wait for the next stable release. I am not sure that this list is the adequate forum for discussing the futex extensions. If somebody says where it should take place and somebody actually declares willingness to work on the implementation side, I can write down my thoughts and post it. - -- ➧ Ulrich Drepper ➧ Red Hat, Inc. ➧ 444 Castro St ➧ Mountain View, CA ❖ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) iD8DBQE/uR8i2ijCOnn/RHQRAut0AKC0zV6s/KcJfvEU8PHFmvfXbu7DdQCgwVfE BpRqDjxHzpUhhbyfmEQ97Hk= =i2+X -----END PGP SIGNATURE----- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
