    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).

    I've been using it for nearly 2 years without any issues whatsoever (I haven't even had to fiddle with it to keep it going). It's been in the kernel for over 1 year.

    They're well beyond "some sort of working version, even if it doesn't do much". Give it a try.

    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?

    Before I committed ANY data to ZFS I sure as heck "played around with it" in virtual machines until I was comfortable doing about anything with it.

    "Pull" one of the drives. What happens?
    dd if=/dev/random of= to your disk in random places (skip/seek), what happens to your data.
    Pull all of the drives and replace it with a larger one.

    How are the user tools for btrfs? zpool & zfs are fairly well documented and have very simple short commands.

    Does it automatically share over nfs/samba like you can with ZFS on Solaris?

    So, what's the deal here - have they pretty much abandoned the old "odd minor releases for development, no new features in stable versions" plan, or what?

    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.

As of next Tuesday, C will be flushed in favor of COBOL. Please update your programs.
