Subject: [PATCH AUTOSEL 5.7 07/30] exfat: Set the unused characters of FileName field to the value 0000h
Date: Wed,  8 Jul 2020 11:40:53 -0400	[thread overview]
Message-ID: <20200708154116.3199728-7-sashal@kernel.org> (raw)
In-Reply-To: <20200708154116.3199728-1-sashal@kernel.org>

From: "Hyeongseok.Kim" <Hyeongseok@gmail.com>

[ Upstream commit 4ba6ccd695f5ed3ae851e59b443b757bbe4557fe ]

Some fsck tool complain that padding part of the FileName field
is not set to the value 0000h. So let's maintain filesystem cleaner,
as exfat's spec. recommendation.
