where is FDSETEMSGTRESH?

You don't need this, you can use floppy_max_errors from <linux/fd.h>.
But you can define it if you want because it is used to know the size of
the target structure (and if alignment or data types differ it can
mismatch. With "int" it's not the case).

This one is for the previous patch. Same comment as above.
