And I'll add a free_filesystem_list () or something similar to it.

Call free_filesystem_list () which I'll add to mountlist.c.

Basically, this is correct - but you only free the 'me' elements. They
contain pointers to malloced memory too.

Freeing the memory again is very system dependent, so this should be done
in mountlist.c
