Subject: [PATCH 2/3] fs/ntfs3: Remove locked argument in ntfs_set_ea
Date: Fri, 24 Sep 2021 19:15:50 +0300	[thread overview]
Message-ID: <b988b38f-ccca-df01-d90d-10f83dd3ad2e@paragon-software.com> (raw)
In-Reply-To: <eb131ee0-3e89-da58-650c-5b84dd792a49@paragon-software.com>

We always need to lock now, because locks became smaller
(see "Move ni_lock_dir and ni_unlock into ntfs_create_inode").
