Subject: [PATCH v3 2/3] fs/ntfs3: Remove locked argument in ntfs_set_ea
Date: Wed, 29 Sep 2021 19:50:21 +0300 [thread overview]
Message-ID: <7584e179-eade-fef9-9da1-39cbb4d1ef32@paragon-software.com> (raw)
In-Reply-To: <1514c7ce-9b2c-fc12-75c4-3b4cfd2639a5@paragon-software.com>
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").
