Ah, this one commit looks good, but the naming of the labels doesn't.

Instead, you should use a name describing what the error path does,
such as "err_free_block2mtd" and "err_destroy_mutex" or something like that.

We have a language full of words with meaning, so it's shame to use
dumb numbers :-)
