In generic/252, aiocp with DIRECT will fail and return EINVAL on 4096 sector size block device, because the default 512 alignment defined in aiocp is not aligned with 4096. Please see the following error: ---------------------------------------------------------- read missing bytes expect 8388608 got -22 ---------------------------------------------------------- We use '-a' option to specify a proper alignment size in all tests that call aiocp with DIRECT.
