Hm, not a nice interface where qemu_close() needs the filename and
(worse) could be given a wrong filename. Maybe it would be better to
maintain a list of fd -> fdset mappings in qemu_open/close?
I agree, I don't really like it either.
We already have a list of fd -> fdset mappings (mon_fdset_fd_t ->
mon_fdset_t). Would it be too costly to loop through all the fdsets/fds
at the beginning of every qemu_close()?
I don't think so. qemu_close() is not a fast path and happens almost
never, and the list is short enough that searching it isn't a problem
anyway.
I agree - just do the loop to do the reverse lookup yourself, rather
than making qemu_close() have a different signature than close().
