Message-ID: <4356fa5f-db35-4e2a-35bb-8f727a08dd63@paragon-software.com>
Date: Mon, 8 May 2023 16:38:46 +0400
From: Konstantin Komarov <almaz.alexandrovich@...agon-software.com>

CC: Linux Kernel Mailing List <linux-kernel@...r.kernel.org>,

Subject: [PATCH 07/10] fs/ntfs3: Code refactoring
Check functions arguments. Use u8 instead of size_t for ntfs names, more
consts and other.
