Hi
This series :
- convert io_handlers to one QLIST
- once there, qemu_set_fd_handlers2() has lots of arguments that are a lot of
times NULL.
Introduce a set of functions to not have to pass NULL values.
- qemu_clear_fd_handlers(): remove it
- qemu_set_fd_read_handler(): only read
- qemu_set_fd_write_handler(): only write
- qemu_set_fd_rw_handler(): read/write
- qemu_set_fd_poll_handler(): it was only used for reads and in qemu-char.c.
- once there fix bt that don't need poll at all (having a poll function that
always return true
is the equivalent of not having one).
- remove cast to (void *)(unsigned long) for things that already were pointers
- IOCanRWHandler is only used for reads -> rename it (almost no users).
ToDo:
- to remove the export of qemu_set_fd_handlers2() we need a solution for tap.
Tap is the only user in qemu that uses poll, read and write, and it changes
in very imaginative
ways:
qemu_set_fd_handler2(s->fd,
s->read_poll ? tap_can_send : NULL,
s->read_poll ? tap_send : NULL,
s->write_poll ? tap_writable : NULL,
s);
No ideas about how to transform this into something that don't use NULL's in
any of its fields
other than a row of if's.
- removal of poll function. comment of qemu_set_fd_handler2()
/* XXX: fd_read_poll should be suppressed, but an API change is
necessary in the character devices to suppress fd_can_read(). */
But qemu-char.c is a complex beast, and would preffer to 1st get this
patches in, and then
work on the other stuff.
- obvious optimization now is to have the FD_SET() for write/read already
filled, but I
haven't done any meassurement.
Comments?

Convert io handlers to QLIST
Introduce qemu_clear_fd_handler()
Introduce qemu_set_fd_read_handler()
Introduce qemu_set_fd_write_handler()
Introduce qemu_set_fd_rw_handler()
bt: remove bt_host_read_poll()
Introduce qemu_set_fd_poll_handler()
remove useless cast
rename IOCanRWHandler to IOCanReadHandler
