But the block layer should be all good now, and David went through all his networking commits an extra time just to make me feel comfy about it, so in the end I didn&#8217;t see any point to making the release cycle any longer than usual.<\/p>\n<p>And on the whole, everything here is pretty small. The diffstat looks a bit larger for an xfs fix, because that fix has three cleanup refactoring patches that precedes it. And there&#8217;s a access type<br \/>\npattern fix in the sound layer that generated lots of noise, but is all very simple in the end.<\/p>\n<p>&#8230;<br \/>\n<\/i><\/ul>\n<p><b>Download and Install Linux Kernel 4.5:<\/b><\/p>\n<blockquote><p><i>NOT recommended for &#8220;normal&#8221; users!
