Subject: [PATCH AUTOSEL 5.13 15/46] udf: Fix iocharset=utf8 mount option
Date: Sun, 5 Sep 2021 21:20:20 -0400 [thread overview]
Message-ID: <20210906012052.929174-15-sashal@kernel.org> (raw)
In-Reply-To: <20210906012052.929174-1-sashal@kernel.org>
From: Pali Rohár <pali@kernel.org>
[ Upstream commit b645333443712d2613e4e863f81090d5dc509657 ]
Currently iocharset=utf8 mount option is broken. To use UTF-8 as iocharset,
it is required to use utf8 mount option.
Fix iocharset=utf8 mount option to use be equivalent to the utf8 mount
option.
If UTF-8 as iocharset is used then s_nls_map is set to NULL. So simplify
code around, remove UDF_FLAG_NLS_MAP and UDF_FLAG_UTF8 flags as to
distinguish between UTF-8 and non-UTF-8 it is needed just to check if
s_nls_map set to NULL or not.
