Subject: [PATCH v4 7/9] fs/ntfs3: Add iocharset= mount option as alias for nls=
Date: Tue,  7 Sep 2021 18:35:55 +0300	[thread overview]
Message-ID: <20210907153557.144391-8-kari.argillander@gmail.com> (raw)
In-Reply-To: <20210907153557.144391-1-kari.argillander@gmail.com>

Other fs drivers are using iocharset= mount option for specifying charset.
So add it also for ntfs3 and mark old nls= mount option as deprecated.
