Subject: [PATCH v3 0/5] zbd: Support zone reset by trim
Date: Fri, 6 Aug 2021 10:07:06 +0900 [thread overview]
Message-ID: <20210806010711.1128153-1-shinichiro.kawasaki@wdc.com> (raw)
Trim workload is currently not supported for zonemode=zbd. This patch series
enables it by resetting zones for trim I/Os. This allows fio to measure
performance of zoned block devices using more realistic workloads which mixes
write and trim.
The first patch prepares for trim support by modifying the helper function
zbd_find_zone(). The second patch adds zone reset for trim. The third patch
enables trim workload for libzbc I/O engine. The fourth patch updates the HOWTO
file to describe the added functionality. The fifth patch adds a test case that
exercises trim operation with zonemode=zbd.
Changes from v2:
* Reflected comments on the cover letter and the 4th patch
Changes from v1:
* Separated HOWTO/man changes from 2nd patch as 4th patch
* Reflected various comments on the list
Shin'ichiro Kawasaki (5):
zbd: Add min_bytes argument to zbd_find_zone()
zbd: Support zone reset by trim
engines/libzbc: Enable trim for libzbc I/O engine
