Yo.
I'm working on a hotswap infrastructure patch right now that would
give you the API necessary to perform a hotswap. There are
essentially two parts:
1) The driver has to recognize that a plug/unplug event occurred
2) libata has to take the appropriate action to plug/unplug a device.
Currently, I have only done step 1) for the sata_promise driver. Step
2) is being... well, written. Since you're doing hotswap stuff,
great, you can test it for me (I am in China until September with no
goddamn hardware to test with)!
Look (tonight, over the next few hours in fact) for messages of the
type "Add disk hotswap support to libata." I should have some patches
sent in by then.
