[Qemu-devel] [PATCH 10/12] iotests: teach FilePath to produce multiple paths
Posted by John Snow 6 years, 4 months ago
Use "FilePaths" instead of "FilePath" to request multiple files be
cleaned up after we leave that object's scope.

This is not crucial; but it saves a little typing.

The example in the comment for FilePaths looks stale now, but it looked
just as stale before.  (“TestFilePath”)
