Brian,

Having agreed on doing one file per attribute, I'm now not sure how to
name them. Maybe you can give me a hand?

Let me add some context: these are the per-MTD partition fields of the
mtd_ecc_stats struct, although two of them aren't related to ECC, but to
the bad blocks management. This is the struct:

struct mtd_ecc_stats {
        __u32 corrected;
        __u32 failed;
        __u32 badblocks;
        __u32 bbtblocks;
};

How about the following?

* corrected_bits
* uncorrectable_errors
* badblocks
* bbtblocks
