From mboxrd@z Thu Jan 1 00:00:00 1970 From: Vishal Verma Subject: [PATCH 0/3] Badblock tracking for gendisks Date: Fri, 20 Nov 2015 17:49:17 -0700 Message-ID: <1448066960-20119-1-git-send-email-vishal.l.verma@intel.com> Return-path: Sender: linux-scsi-owner@vger.kernel.org To: linux-nvdimm@lists.01.org Cc: Vishal Verma , linux-block@vger.kernel.org, linux-raid@vger.kernel.org, linux-scsi@vger.kernel.org, Jens Axboe , NeilBrown , Jeff Moyer List-Id: linux-raid.ids Patch 1 copies badblock management code into a header of its own, making it generally available. It follows common libraries of code such as linked lists, where anyone may embed a core data structure in another place, and use the provided accessor functions to manipulate the data. Patch 2 adds badblock tracking to gendisks (in preparation for use by NVDIMM devices). Right now, it is turned on unconditionally - I'd appreciate comments on if that is the right path. Patch 3 converts md over to use the new badblocks 'library'. I have done some pretty simple testing on this - created a raid 1 device, made sure the sysfs entries show up, and can be used to add and view badblocks. A closer look by the md folks would be nice here.
