[Qemu-devel] [PATCH 0/5] iohandlers: Add support for enabling/disabling individual handlers

[Amit Shah <amit.shah@redhat.com>]

Hi,

This patchset adds new interfaces to work with iohandlers.  It adds:

int assign_fd_handlers(int fd, IOHandlerOps *ops, void *opaque)
   -- Specify io handlers for an fd
int remove_fd_handlers(int fd)
   -- Remove fd handlers for fd (mark ioh for deletion)
int set_read_poll_fd_action(int fd, bool enable)
   -- Enable or disable the fd_read_poll fd handler
int set_read_fd_action(int fd, bool enable)
   -- Enable or disable the fd_read fd handler
int set_write_fd_action(int fd, bool enable)
   -- Enable or disable the fd_read fd handler

A new struct, IOHandlerOps, is added, to collect all the ops together
instead of passing individual ones to functions.

The older function, qemu_set_fd_handler2(), is now a wrapper to
assign_fd_handlers()  and can be deprecated by converting the existing
usage to assign_fd_handlers().

Please apply.

Amit Shah (5):
  iohandlers: Avoid code duplication
  iohandlers: Introduce assign_fd_handlers() and remove_fd_handlers
  iohandlers: Allow each iohandler to be enabled/disabled individually
  iohandlers: Enable an iohandler only if the associated handler exists
  iohandlers: Add IOHandlerOps struct
