From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mark Hills Subject: First observations with bcache Date: Sat, 10 Sep 2011 14:44:56 +0100 (BST) Message-ID: <1109101110320.2733@stax.localdomain> Mime-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Return-path: Sender: linux-bcache-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-bcache-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-Id: linux-bcache@vger.kernel.org I took some time to try out bcache, on an x86 Dell PC with OCZ Agility 3 SSD. The good news is that once I had applied various workarounds, thing seems to work as expected, both with 2.6.34 and with an updated 3.1 branch. I had to make a few modifications to get going, and then more to enable the various debug options. The most awkward problems seem to be the result of 32-bit architecture, and I think are highlighted by building as a module. I'll follow-up this email with the patches (based on bcache-3.1 branch), though I don't consider them to be long-term solutions; they show the changes I made. I some cases I've proposed a better solution, but thought I'd raise them here for discussion first. -- Mark
