Kernel locking

Well I'm glad they officially fixed the kernel lock. Out of curiosity, how long until Ubuntu or Debian sees this integrated into their line? A year? Not trolling, I only started using Ubuntu recently, so I'm curious.

Ubuntu in about 6 months, 2.6.37 should be in the 11.04 release.

In Debian Stable - in about 2 years (in the next release).

Would someone mind explaining (for those of us who have some C experience, but aren't kernel hackers) what the Big Kernel Lock is? In particular, is this something that will impact the desktop user?

And this is one example of why the kernel doesn't have a stable ABI. You can bet tons of unmaintained third party drivers would use the BKL, so you could never get rid of it. From what I've understood purging it from every driver has been a pretty big job and only possible because all the drivers are in the kernel tree.
