Why not:
const int len = sizeof(device->fs_info->sb->s_id)
+ sizeof("(device )") - 1;
char devstr[len];
len is used only once for snprintf to devstr, so there it can be
replaced by sizeof(devstr) and the sizeof()+sizeof() can be used for
devstr declaration.
That's better. I'll fix in that way.
The size of devstr seems to be one byte shorter than needed:

There's a leading " " at the begining that I don't see accounted for.
Oops, I'll fix. Thanks.
