Note the issue that others have pointed out to you: OpenSolaris is probably more interested in picking up code from Linux than the other way around! :-) You mentioned "dtrace" and "ZFS". Firstly, Linux already has a "dtrace" equivalent. Secondly, ZFS might be interesting in theory, although our prior experience of having compatibly-licensed filesystems ported over to Linux has been pretty negative: XFS ended up being an integration nightmare - and that doesnt have to do anything with the qualities of XFS (it's one of the cleanest Linux filesystems, if not the cleanest), the problem is that components within a kernel are very tightly integrated and rarely does it make sense to port over more than just drivers or maybe libraries. And that's i guess what OpenSolaris lacks and which i suspect it is mostly interested in: lots of nice Linux drivers ;-) XFS, the largest Linux filesystem is 100K lines of code - and ZFS (i've never seen it) is very likely smaller than that. Linux drivers on the other hand, as of today, are _3.7 million_ lines of code and enable Linux to run on 99% of the hardware that is produced today. Guess which one has the larger strategic significance? ;-) Ingo - 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/
