Agenda topic proposal: ---------------------- In the past year a lot of work has been done towards more efficient Linux discard support. We would like to review all the efforts in this area and summarize where we stand now and what can be done in the near future. Show the options we have and how they perform with various classes of devices in different benchmarks and present some numbers. Last, but not least we think that we are at the point where hardware vendors should join in the discussion. At this matter we would like to outline the options they have to test the Linux discard stack with their hardware and make it all cooperate easily. Authors: -------- Christoph Hellwig <hch@xxxxxxxxxxxxx> Christoph Hellwig has been working with Linux for more than 10 years, soon focussing on kernel-related issues. He has also been involved in various other Free Software projects. After a number of smaller network administration and programming contracts he worked for Caldera's German development subsidiary on various kernel and userlevel aspects of the OpenLinux distribution and later joined the filesystem and storage group at SGI, focussing on XFS for Linux. Since 2004 he has been self-employed doing contracting, consulting and training in the Linux Kernel and Storage world. Lukas Czerner <lczerner@xxxxxxxxxx> Lukas is a software engineer with Red Hat, Inc, where he works mainly on Ext4 filesystem. He has been involved in performance evaluation of Linux discard support and was examining of alternative approaches which led to establishing the interface for filesystem batched discard support aka FITRIM as well as implementation for Ext4/3 filesystems.
