v1 -> v2: - replace both run-tests-against-conventional-nullb and run-tests-against-conventional-nullb with a single script, run-tests-against-nullb, that runs test-zbd-support unit tests over a variety of different zoned configurations. - add five new test cases to test-zbd-support to cover the code changes made in zbd.c as a part of this series. - mark all test cases in test-zbd-support script that are not applicable for the device configuration as SKIP instead of reporting them as passed. - properly handle writes to conventional zones that cross over to sequential zones. - make additional improvements in zone locking parts of zbd.c. - implement miscellaneous test script enhancements. This patch series contains bug fixes and refactoring changes related to support for Zoned Block Devices (ZBD) in fio. The highlights: - fix several errors related to running workloads that span a mix of conventional zones and write pointer zones. - improve counting of sectors with data (SWD). - remove dependencies on particular zone types in the code. - add code to gracefully handle offline zones. Aravind Ramesh (1): zbd: initialize sectors with data at start time Dmitry Fomichev (23): zbd: return ENOMEM if zone buffer allocation fails zbd: use zbd_zone_nr() more actively in the code zbd: add get_zone() helper function zbd: introduce zone_unlock() zbd: engines/libzbc: don't fail on assert for offline zones zbd: remove dependency on zone type during i/o zbd: skip offline zones in zbd_convert_to_open_zone() zbd: avoid zone buffer overrun zbd: don't unlock zone mutex after verify replay zbd: use zone_lock() in zbd_process_swd() zbd: don't log "zone nnnn is not open" message zbd: handle conventional start zone in zbd_convert_to_open_zone() zbd: improve replay range validation zbd: set thread errors in zbd_adjust_block() t/zbd: check for error in test #2 t/zbd: add run-tests-against-nullb script t/zbd: add an option to bail on a failed test t/zbd: prevent test #31 from looping t/zbd: add checks for offline zone condition t/zbd: add test #54 to exercise ZBD verification t/zbd: show elapsed time in test-zbd-support t/zbd: increase timeout in test #48 t/zbd: avoid looping on invalid command line options Shin'ichiro Kawasaki (12): zbd: do not lock conventional zones on I/O adjustment zbd: do not set zbd handlers for conventional zones zbd: count sectors with data for write pointer zones zbd: initialize min_zone and max_zone for all zone types zbd: disable crossing from conventional to sequential zones t/zbd: add -t option to run-tests-against-nullb t/zbd: skip tests when test prerequisites are not met t/zbd: skip tests that need too many sequential zones t/zbd: test that conventional zones are not locked during random i/o t/zbd: test that zone_reset_threshold calculation is correct t/zbd: test random I/O direction in all-conventional case t/zbd: fix wrong units in test case #37 Makefile | 5 +- engines/libzbc.c | 2 +- oslib/linux-blkzoned.c | 2 +- t/run-fio-tests.py | 8 +- t/zbd/functions | 56 +++- t/zbd/run-tests-against-nullb | 329 ++++++++++++++++++++++++ t/zbd/run-tests-against-regular-nullb | 27 -- t/zbd/run-tests-against-zoned-nullb | 53 ---- t/zbd/test-zbd-support | 301 +++++++++++++++++++--- zbd.c | 354 ++++++++++++++++---------- zbd.h | 5 + 11 files changed, 883 insertions(+), 259 deletions(-) create mode 100755 t/zbd/run-tests-against-nullb delete mode 100755 t/zbd/run-tests-against-regular-nullb delete mode 100755 t/zbd/run-tests-against-zoned-nullb -- 2.28.0
