Hey Rusty, This patchset is on top of the previous one. It sends a SIGIO signal to apps that request signals for host activity. SIGIO is sent on host connect, disconnect as well as hot-unplug (which can be seen as a special case of host disconnect). Tested using several testcases in the test-virtserial repo: http://fedorapeople.org/gitweb?p=amitshah/public_git/test-virtserial.git Please apply.

Hi Rusty, The main thing in these patches is the introduction of injecting SIGIO on host-side connect/disconnect events and when new data is available for ports. The first two patches fix bugs that I haven't seen, but look like the right thing to do. These have been tested extensively using the test-virtserial test suite. Please apply, Amit.
