mtdblock: make warning messages ratelimited

2023-07-27T15:16:14+00:00

When exercising various dev interfaces with stress-ng the mtdblock drivers can be (ab)used to generate a lot of warning messages. Make these rate limited to reduce the kernel log from being spammed with the same messages.

mtdblock: tolerate corrected bit-flips

mtd_read() may return -EUCLEAN in case of corrected bit-flips.This particular condition should not be treated like an error. Signed-off-by: Bang Li Signed-off-by: Miquel Raynal Link: https://lore.kernel.org/linux-mtd/20230314165653.252673-1-libang.linuxer@gmail.com

mtdblock: Warn if added for a NAND device

2021-08-17T16:41:59+00:00

There is a surprisingly large number of tutorials that suggest using mtdblock to mount SquashFS filesystems on flash devices, including NAND devices. This approach is suboptimal than using UBI. If the flash device is NAND, this is specially true, due to wear leveling, bit-flips and badblocks. In this case UBI is strongly preferred, so be nice to users and print a warning suggesting to consider UBI block, if mtdblock is added for a NAND device.
