The kernel commit de3510e52b0a ("null_blk: fix command timeout completion handling") fixed null_blk driver to report ETIMEDOUT errors for IO operations failed with a timeout. This change causes the dd call in block/014 case to print the following error message: dd: error reading '/dev/nullb0': Connection timed out The presence of this message result in a failure of the test case even without a kernel crash or hang, which is what the block/014 case is testing. Avoid this failure by ignoring dd error messages using a redirection of dd stderr to /dev/null.
