Max Reitz e7e08380c3 iotests: qcow2 COW with minimal L2 cache size 
This adds a test case to test 103 for performing a COW operation in a
qcow2 image using an L2 cache with minimal size (which should be at
least two clusters so the COW can access both source and destination
simultaneously).

README 

=== This is the QEMU I/O test suite ===

* Intro

This package contains a simple test suite for the I/O layer of qemu.
It does not require a guest, but only the qemu, qemu-img and qemu-io
binaries.  This does limit it to exercise the low-level I/O path only
but no actual block drivers like ide, scsi or virtio.

* Usage

Just run ./check to run all tests for the raw image format, or ./check
-qcow2 to test the qcow2 image format.  The output of ./check -h explains
additional options to test further image formats or I/O methods.

* Feedback and patches

Please send improvements to the test suite, general feedback or just
reports of failing tests cases to qemu-devel@savannah.nongnu.org.
