Hi Jens, The 1st patch removes the liburing ublk test source, and the 2nd patch adds the test back with the kernel ublk selftest source. The original test case is covered, and io_uring kernel fixed buffer and ublk zero copy is covered too. Now the ublk source code is one generic ublk server implementation, and test code is shell script, this way is flexible & easy to add new tests.
