Subject: iotests: Fix 291 across more file systems
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=adf92f4645ba46726368735916fed763d3e5a09b;p=qmiga%2Fqemu.git

iotests: Fix 291 across more file systems

Depending on the granularity of holes and amount of metadata consumed
by a file, the 'disk size:' number of 'qemu-img info' is not reliable.
Adjust our test to use a different set of filters to avoid spurious
failures.
