Hello Jens, This patch series that adds zoned block device support to fio. The pull request on github is in sync with this patch series. Please consider these patches for the upstream fio repository. Thanks, Bart. Changes compared to the version posted earlier this morning: - zbd_init() is only called for zonemode=zbd. - If the first I/O fails with EIO (null_blk in zoned mode) or EREMOTEIO (SCSI zoned block device) then fio suggests to use zonemode=zbd. - A new test (test45) has been added that verifies that this message is reported if applicable. Bart Van Assche (11): configure: Add <linux/blkzoned.h> test Add the 'zbd' debug level Add the zonemode job option Introduce the io_u.post_submit callback function pointer Pass offset and buffer length explicitly to mark_random_map() Add two assert statements in mark_random_map() Add support for zoned block devices Collect and show zone reset statistics Make it possible to limit the number of open zones Add support for resetting zones periodically Add scripts for testing the fio zoned block device support code HOWTO | 88 +- Makefile | 3 + cconv.c | 2 + configure | 21 + debug.h | 1 + file.h | 8 + filesetup.c | 15 +- fio.1 | 76 +- fio.h | 2 + init.c | 29 +- io_u.c | 55 +- io_u.h | 6 + ioengines.c | 12 + options.c | 70 ++ stat.c | 13 +- stat.h | 3 + t/zbd/functions | 106 ++ t/zbd/run-tests-against-regular-nullb | 25 + t/zbd/run-tests-against-zoned-nullb | 27 + t/zbd/test-zbd-support | 817 ++++++++++++++++ thread_options.h | 17 + zbd.c | 1288 +++++++++++++++++++++++++ zbd.h | 142 +++ 23 files changed, 2783 insertions(+), 43 deletions(-) create mode 100644 t/zbd/functions create mode 100755 t/zbd/run-tests-against-regular-nullb create mode 100755 t/zbd/run-tests-against-zoned-nullb create mode 100755 t/zbd/test-zbd-support create mode 100644 zbd.c create mode 100644 zbd.h -- 2.18.0
