This was done on VAXen and in Mach ages ago.
I know nothing about that ancient stuff, but I've to trust you on this. > On Linux, there've already been two implementations, one by Hugh > Dickens and an expanded version by Bill Irwin (presented at OLS in > 2003). > > Bill's patch was notable for going to heroic efforts to maintain > binary compatibility, basically separating the userspace notion of the > ABI's page size from the kernel's. How's your version fair here? The events I referred to happened well before Bill's effort. I admit I also started having some doubt about the correctness of my above statement when I read Hugh's patch dated Jul 2001 in the last few days, I'm now uncertain when Hugh's effort started, probably many months before he published his code. Overall I definitely shooted myself in the foot ;), because 1) I don't actually care that much about the attribution of the idea (I wrote it only as a side note), 2) we're in open source intellectual property destruction land anyway so it doesn't matter who had the idea. Apologies. The way I felt while writing that side note, was that the time has come to do what we had planned a long time ago, I simply didn't care too much if VAXen or other ancient OS had it working before, sorry. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
