From d81e06be921f90d5f1bada59d4549ca6f1bedc61 Mon Sep 17 00:00:00 2001 From: Konstantin Komarov Date: Fri, 24 Sep 2021 17:50:22 +0300 Subject: [PATCH] fs/ntfs3: Remove locked argument in ntfs_set_ea We always need to lock now, because locks became smaller (see d562e901f25d "fs/ntfs3: Move ni_lock_dir and ni_unlock into ntfs_create_inode").
