From 3db3c3fb840ed4a6c7666d1464959edd40fe54f1 Mon Sep 17 00:00:00 2001 From: Tetsuhiro Kohada Date: Tue, 23 Jun 2020 15:22:19 +0900 Subject: exfat: write multiple sectors at once Write multiple sectors at once when updating dir-entries. Add exfat_update_bhs() for that. It wait for write completion once instead of sector by sector. It's only effective if sync enabled.
