And since we already have existing usage of one spelling, switching the spelling now would require a deprecation period and is separate from this patch.

Seems reasonable. The real reason why I'm changing 059 is that zeroed_grain=on works only with some subformats and the test case tests many different subformats, including those for which it doesn't work. Kevin

In order to avoid bitrot in the zero cluster code in VMDK, enable zero_grained=on by default for the tests. Signed-off-by: Kevin Wolf <kwolf@redhat.com> --- tests/qemu-iotests/059 | 6 +++--- tests/qemu-iotests/check | 3 +++ 2 files changed, 6 insertions(+), 3 deletions(-)
