[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: OGAWA Hirofumi <hirofumi@xxxxxxxxxxxxxxxxxx>

[ 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.
