From dc9629faef0a3d3cd35aff22806376700275a8b6 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 8 Jan 2026 15:19:02 +0100 Subject: [PATCH] fs: allow error returns from generic_update_time Now that no caller looks at the updated flags, switch generic_update_time to the same calling convention as the ->update_time method and return 0 or a negative errno. This prepares for adding non-blocking timestamp updates that could return -EAGAIN.
