Namjae Jeon f0aac6162e fat: use fat_msg_ratelimit() in fat__get_entry() ... If an application tries to lookup (opendir/readdir/stat) 5000 files on a fatfs USB device and the device is unplugged, many message occur, shown below. This makes the application slow. So use the new fat_msg_ratelimit() decrease the messaging rate. #> ./file_lookup_testcase ./files_directory/ usb 2-1.4: USB disconnect, device number 4 FAT-fs (sda1): FAT read failed (blocknr 2631) FAT-fs (sda1): Directory bread(block 396816) failed FAT-fs (sda1): Directory bread(block 396817) failed FAT-fs (sda1): Directory bread(block 396818) failed FAT-fs (sda1): Directory bread(block 396819) failed FAT-fs (sda1): Directory bread(block 396820) failed FAT-fs (sda1): Directory bread(block 396821) failed FAT-fs (sda1): Directory bread(block 396822) failed FAT-fs (sda1): Directory bread(block 396823) failed FAT-fs (sda1): Directory bread(block 406824) failed FAT-fs (sda1): Directory bread(block 406825) failed FAT-fs (sda1): Directory bread(block 406826) failed FAT-fs (sda1): Directory bread(block 406827) failed FAT-fs (sda1): Directory bread(block 406828) failed FAT-fs (sda1): Directory bread(block 406829) failed FAT-fs (sda1): Directory bread(block 406830) failed FAT-fs (sda1): Directory bread(block 406831) failed FAT-fs (sda1): Directory bread(block 417696) failed FAT-fs (sda1): Directory bread(block 417697) failed FAT-fs (sda1): Directory bread(block 417698) failed FAT-fs (sda1): Directory bread(block 417699) failed FAT-fs (sda1): Directory bread(block 417700) failed FAT-fs (sda1): Directory bread(block 417701) failed FAT-fs (sda1): Directory bread(block 417702) failed FAT-fs (sda1): Directory bread(block 417703) failed FAT-fs (sda1): FAT read failed (blocknr 2631) FAT-fs (sda1): Directory bread(block 396816) failed FAT-fs (sda1): Directory bread(block 396817) failed FAT-fs (sda1): Directory bread(block 396818) failed FAT-fs (sda1): Directory bread(block 396819) failed FAT-fs (sda1): Directory bread(block 396820) failed FAT-fs (sda1): Directory bread(block 396821) failed Signed-off-by: Namjae Jeon <linkinjeon@gmail.com> Signed-off-by: Amit Sahrawat <amit.sahrawat83@gmail.com> Acked-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2012-05-31 17:49:28 -07:00
