Subject: [PATCH AUTOSEL 5.10 13/26] fat: add ratelimit to fat*_ent_bread()
Date: Wed, 1 Jun 2022 09:57:46 -0400 [thread overview]
Message-ID: <20220601135759.2004435-13-sashal@kernel.org> (raw)
In-Reply-To: <20220601135759.2004435-1-sashal@kernel.org>
From: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp>
[ Upstream commit 183c3237c928109d2008c0456dff508baf692b20 ]
fat*_ent_bread() can be the cause of too many report on I/O error path.
So use fat_msg_ratelimit() instead.
