From d5cf09baced0ef3d2cc118865079f8b129e98e2f Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 30 Jul 2014 09:12:05 +1000 Subject: xfs: require 64-bit sector_t Trying to support tiny disks only and saving a bit memory might have made sense on an SGI O2 15 years ago, but is pretty pointless today. Remove the rarely tested codepath that uses various smaller in-memory types to reduce our test matrix and make the codebase a little bit smaller and less complicated.
