From be17b1ccd4e82a66b9d9676dec8edce137e967d8 Mon Sep 17 00:00:00 2001 From: Yuezhang Mo Date: Wed, 29 Jun 2022 11:05:51 +0800 Subject: exfat: remove duplicate write inode for extending dir/file Since the timestamps need to be updated, the directory entries will be updated by mark_inode_dirty() whether or not a new cluster is allocated for the file or directory, so there is no need to use __exfat_write_inode() to update the directory entries when allocating a new cluster for a file or directory.
