Krishna, The kernel side interface for zone append to raw block devices is not yet sorted out. That interface needs to be fixed first and we can then think of fio patching. Without a clear idea of what the kernel interface and its semantic will be, I do not think that commenting on your current code will be useful. > > Ankit Kumar (2): > Add Zone Append command support > libaio: support for Zone Append command > > Krishna Kanth Reddy (1): > t/zbd: Add support to verify Zone Append command with libaio tests > > HOWTO | 7 +++++++ > engines/libaio.c | 32 ++++++++++++++++++++++++++++---- > fio.1 | 7 +++++++ > ioengines.c | 6 ++++++ > ioengines.h | 3 ++- > options.c | 10 ++++++++++ > t/zbd/test-zbd-support | 29 +++++++++++++++++++++++++++++ > thread_options.h | 2 ++ > 8 files changed, 91 insertions(+), 5 deletions(-) > -- Damien Le Moal Western Digital Research
