From 9e0c8e148d5d7240e540f825546a434a24ac2660 Mon Sep 17 00:00:00 2001 From: Zhao Lei Date: Wed, 23 Sep 2015 15:19:06 +0800 Subject: [PATCH] btrfs-progs: tests: Introduce misc-tests/008-leaf-crossing-stripes To check is btrfs-convert create bad filesystem with leaf across stripes. It is happened in progs version <=v4.1.2, and fixed by patch titled: btrfs: convert: Avoid allocating metadata extent crossing stripe boundary which was merged in v4.2. Notice thar this testcase can not report error in old version of btrfs-progs, because "btrfs check" can't check this type of error in those version, but we have another testcase in fsck-tests, to check is "btrfs check" support this check. So, the above 2 testcase together can check leaf-crossing-stripes bug in all versions.
