The schedule I heard from Linus at the kernel summit was that both changes were to go in between 2.5.1 and 2.5.2. I would prefer sooner than later because I'm *really* *tired* of maintaining a parallel rulebase. -- Eric S.

The tendency is for taxpayers to try to take more control of their finances .. -- IRS Strategic Plan, (May 1984) - 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/
