    Phoronix: BCache For The Linux Kernel Still Being Tackled

    BCache for the Linux kernel is still being worked on and is now up to its thirteenth revision prior to being merged into the mainline Linux kernel. BCache provides write-through and write-back caching as a new block device...

    Yeah, sure

    Yeah sure, include it! Linux can't boot and stops with a usb stick plugged in, but who cares. Lets give it another wear out for HDD. And use zeitgeist for indexing. Its going to be awesome spyware called ultimate linux spyware. Sure. go with it.

    and....


    Linux has always been a fight with windmills for me. Always something, always a shit comes in the way. Always. Why there cannot anything be normal. Jesus I am just a normal person. Just want to turn the computer and forget the geek stuff. Plug and Play.

    Here's what I've encountered. And apparently there has been no no solution and nobody in a billion dollar companies want to make a small change. One clever person with $ 75k p.a. would be sufficient. But noooo. They have to sweam in honey and tell people to GFT.

    and the winners are:

    *Intel= ugly video tearing, some window tearing, crushing under vaapi, freezing menus, system crashes under file dragging

    *AMD= Catalysts/fglrx = choppy video playback, disgusting video tearing, ugly window tearing, complete instability leading to crashes

    *Nvida= ugly video tearing, tearing windows, videos freezing with NVDPAU, no crashes.Linux has no use for end user whatsoever.

    And yet NO SYNC TO VBLANK for any graphics. SHAME and DISGUST!

    The major question is WHEEEEEEEEEEN is the fix coming? Who of any Linux coders and contributors to Xorg or kernel called them? Does anyone including Linus watches videos under Linux? Apparently not. Apple OS and Android do not have these issues, so who gives a fuck? Right? The most important is that the shitty spywarey mess from google named Android is included in the kernel, because everyone on their laptops and desktops need that shit, I believe. The need of Torvalds to work for Google is more important. Wee don't give a fuck about Google. We useers will not work for Google or intend to work. We are just a bunch of morons who want to watch videos on their computers. But who gives a fuck. GFY yousers.


    Honorable mention:
    Kernel Developers:
    9months, Ralink 5390sta pci WiFi has been open sourced and released under GPL, but yet we still have to deal with bad 2800pci for donkeys versions of kernel releases. WTF? Under Windows the latest drivers are like Lamborghini with a tank torque. 2800pci? Shove the up yours.?

      Would this really constitute the kind of user space breakage that Linus, justifiably, tries to avoid? Although it would be using the dm mechanism, it presumably would only break in the specific case of using dm to expose the bcache, not dm as a whole. IOW, dm should function as normal for anyone not using bcache.

        Interesting, is there no write-around cache mode like in flashcache and ZFS (ARC is basically this)? That makes it kind of difficult to get good performance when you're caching on SSDs with slower write speeds (X25-V, for example).

        I've only done a quick skim of the documentation, but it's not clear whether reads also cache to the device; from there, you could get most of the way to write-around by disabling write-time caching.

          Looks very interesting, especially for high-availability tasks that thus far took SSD's with a grain of salt.

            Oh, stupid troll. Better stick to masters of spyware in the universe and their messed up systems.

              Is BCache good for me?

              I use Ubuntu.

              Things I do is listen to music, watch movies, download stuff, email, social networking, some gaming and lots of porno.
