From 2e58edbdf45b901558dffe98933d19bdb510b35b Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Mon, 27 Jun 2016 15:50:11 +0800 Subject: [PATCH] btrfs-progs: convert-test: Add test case for discontinuous hole extent For ext* fs containing a large hole(larger than 128M), btrfs-convert will only insert one 128M hole extent and skip the remaining. This leads to discontinuous file extents. Add test case for it, and since it's a pinpoint regression test case, no combination of convert options nor checksum verification.
