2011-03-09ide: Convert to bdops->check_events()Tejun Heo
Convert ->media_changed() to the new ->check_events() method. The conversion is mostly mechanical. The only notable change is that cdrom now doesn't generate any event if @slot_nr isn't CDSL_CURRENT. It used to return -EINVAL which would be treated as media changed. As media changer isn't supported anyway, this doesn't make any difference. This makes ide emit the standard disk events and allows kernel event polling. Currently, only MEDIA_CHANGE event is implemented. Adding support for EJECT_REQUEST shouldn't be difficult; however, given that ide driver is already deprecated, it probably is best to leave it alone.

2009-04-19ide-cd: convert to using generic sense requestBorislav Petkov
Preallocate a sense request in the ->do_request method and reinitialize it only on demand, in case it's been consumed in the IRQ handler path. The reason for this is that we don't want to be mapping rq to bio in the IRQ path and introduce all kinds of unnecessary hacks to the block layer. tj: * Both user and kernel PC requests expect sense data to be stored in separate storage other than drive->sense_data. Copy sense data to rq->sense on completion if rq->sense is not NULL. This fixes bogus sense data on PC requests. As a result, remove cdrom_queue_request_sense.

2009-02-25ide: fix refcounting in device driversBartlomiej Zolnierkiewicz
During host driver module removal del_gendisk() results in a final put on drive->gendev and freeing the drive by drive_release_dev(). Convert device drivers from using struct kref to use struct device so device driver's object holds reference on ->gendev and prevents drive from prematurely going away. Also fix ->remove methods to not erroneously drop reference on a host driver by using only put_device() instead of ide*_put().

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
