Subject: [PATCH 5/5] fs/ntfs3: Refactoring lock in ntfs_init_acl
Date: Wed, 22 Sep 2021 19:20:49 +0300	[thread overview]
Message-ID: <ed6426f4-a579-86ce-a54f-ac356991a797@paragon-software.com> (raw)
In-Reply-To: <2771ff62-e612-a8ed-4b93-5534c26aef9e@paragon-software.com>

This is possible because of moving lock into ntfs_create_inode.
