| Subject: fat: add ratelimit to fat*_ent_bread() |
| |
| 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. |
