Message-ID: <710ec5d1-adbf-4ce5-50a5-8b8266ccb672@rqc.ru> Date: Mon, 4 Sep 2017 12:31:54 +0300 MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8; format=flowed Sender: linux-btrfs-owner@vger.kernel.org List-ID: Hello list, good time of the day, More than once I see mentioned in this list that autodefrag option solves problems with no apparent drawbacks, but it's not the default. Can you recommend to just switch it on indiscriminately on all installations? I'm currently on kernel 4.4, can switch to 4.10 if necessary (it's Ubuntu that gives us this strange choice, no idea why it's not 4.9). Only spinning rust here, no SSDs. -- With Best Regards, Marat Khalili
