From 9245b4adb1242589f9ffdd08cf6e529f46b2de7a Mon Sep 17 00:00:00 2001 From: Konstantin Komarov Date: Fri, 22 May 2026 14:58:12 +0200 Subject: [PATCH] fs/ntfs3: force waiting for direct I/O completion It makes ntfs3 wait for direct I/O completion before returning to the caller, instead of allowing the write path to complete asynchronously. The issue was discovered during internal tests.
