Subject: [PATCH v3 0/8] Introduce the end_syncfs option
Date: Fri, 27 Feb 2026 14:55:30 +0900 [thread overview]
Message-ID: <20260227055538.2334916-1-dlemoal@kernel.org> (raw)
Jens, Vincent,
This patch series introduces the end_syncfs option and adds support for
it to the main IO engines that can handle regular files.
This new option improves the precision of file system benchmarks when a
large number of files are being handled.
Changes from v2:
- Reworked patch 1 to build a list of file system mounts per job and
have the end_syncfs option issue syncfs() call for eacho mounted file
system when a job write stage completes.
- Added patch 2 to 7 to support this new option in hte sync, libaio,
io_uring, fallocate, fileoperations, ftruncate and posixaio IO
engines.
