Thanks for the review, Rusty. The result is:

 drivers/char/Kconfig          |    5 -
 drivers/char/virtio_serial.c  |  160
++++++++++++++++++------------------------
 include/linux/virtio_serial.h |    3

Major changes since the last version are:

- add support for poll()
- return as much data as possible for read()
- fix memleaks
- remove ioctl code
- other cleanups suggested by Rusty

Thanks,
		Amit
