[Qemu-devel] [PATCH v4 00/13] main-loop: Get rid of fd_read_poll and qem


From: Fam Zheng
Subject: [Qemu-devel] [PATCH v4 00/13] main-loop: Get rid of fd_read_poll and qemu_set_fd_handler2
Date: Thu, 4 Jun 2015 14:45:11 +0800

v4: Remove unnecessary variable "can_send" in 06. [Stefan, Jason]

This carries out the mandate in the comment of qemu_set_fd_handler2 and removes
fd_read_poll from the code base, because it will make the work easier to
convert ppoll to epoll in main loop, as well as convert iohandler to GSource.
Also, the aio interface doesn't have a read poll callback, which means this
conversion woule be necessary if we want to move things from main loop to
AioContext.

There are five users of the read poll callback now: qemu-nbd, l2tpv3, netmap,
socket and tap.

Patch 1 adds a stub for qemu_set_fd_handler which will be referenced in coming
patches.

Patch 2 converts qemu-nbd which compares two global numbers in the fd_read_poll
callback.

Patches 2~5 converts the four net devices, all of which checks
qemu_can_send_packet() in the callback.

Patch 6 and 7 finally removes the function.

The rest of the series is cleaning up of dead code.

Please review!
