[PATCH] iotests: Fix 291 across more file systems
Posted by Eric Blake 3 years, 11 months ago
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.

Thanks, applied to the block branch.

It has a conflict with one of Vladimir's bitmaps patches that I'm about 
to send a pull request for; so I'll resolve the conflict and include it 
in my bitmaps tree instead, and you can drop it from yours.  I'm 
assuming I can add your Acked-by since you were willing to stage it.

Ok, no problem.
