[Qemu-devel] [PATCH] iotest: Fix filtering order in 226

[Max Reitz]

The test directory should be filtered before the image format, otherwise
the test will fail if the image format is part of the test directory,
like so:

[...]
-can't open: Could not open 'TEST_DIR/t.IMGFMT': Is a directory
+can't open: Could not open '/tmp/test-IMGFMT/t.IMGFMT': Is a directory
[...]

Maybe we should start writing tests for our tests? ;-)

Thanks, applied to the block branch.
