From 389d34f0ab02c34115b9c5292dc1efd3be10a8e2 Mon Sep 17 00:00:00 2001 From: Jan Prusakowski Date: Fri, 30 May 2025 09:23:49 +0000 Subject: [PATCH] f2fs/004: avoid race condition in test In current implementation the atomic write may not start before the direct write and the test fails. The patch adds a delay after starting the atomic write process so it has a chance to actually start wrtiting data and set the internal state of the file correctly.
