The usual way is to use the expunges, but as this is a feature coverage, I think the test should detect if the kernel has the feature at all. Similar to the fallocate modes etc. For the test itself, the scenarios look sufficient, so Reviewed-by: David Sterba <dsterba@xxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe fstests" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
