From 8a9d6e964d318533ba3d2901ce153ba317c99a89 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 5 Aug 2017 10:59:14 +0200 Subject: [PATCH] pnfs/blocklayout: require 64-bit sector_t The blocklayout code does not compile cleanly for a 32-bit sector_t, and also has no reliable checks for devices sizes, which makes it unsafe to use with a kernel that doesn't support large block devices.
