Raw Normal View History

Linux-2.6.12-rc2 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!

cdrom: add ->check_events() support In principle, cdrom just needs to pass through ->check_events() but CDROM_MEDIA_CHANGED ioctl makes things a bit more complex. Just as with ->media_changed() support, cdrom code needs to buffer the events and serve them to ioctl and vfs as requested. As the code has to deal with both ->check_events() and ->media_changed(), and vfs and ioctl event buffering, this patch adds check_events caching on top of the existing cdi->mc_flags buffering.

cdrom: move shared static to cdrom_device_info The keeplocked variable in the cdrom driver is shared across multiple drives, but set in per-device ioctls.
