From b45adcbdf48df5f488f118bc459e1fc7a94ace68 Mon Sep 17 00:00:00 2001 From: Gao Xiang Date: Wed, 28 Aug 2024 17:52:32 +0800 Subject: [PATCH] erofs: clean up erofs_register_sysfs() After commit 684b290abc77 ("erofs: add support for FS_IOC_GETFSSYSFSPATH"), `sb->s_sysfs_name` is now valid. Just use it to get rid of duplicated logic.
