[Qemu-devel] [PATCH v1 16/23] tests/qemu-iotests/005: Add a sanity check

From: Alex Bennée
Subject: [Qemu-devel] [PATCH v1 16/23] tests/qemu-iotests/005: Add a sanity check for large sparse file support
Date: Thu, 9 May 2019 17:59:04 +0100

From: Thomas Huth <address@hidden>

"check -raw 005" fails when running on certain filesystems - these do not
support such large sparse files. Use the same check as in test 220 to
skip the test in this case.
