Revert "pktcdvd: remove driver." This reverts commit f40eb99897af665f11858dd7b56edcb62c3f3c67. There are apparently still users out there of this driver. While we'd love to remove it to ease the maintenance burden, let's reinstate it for now until better (userspace) solutions can be developed.

pktcdvd: convert to use attribute groups There is no need to create kobject children of the pktcdvd device just to display a subdirectory name. Instead, use a named attribute group which removes the extra kobjects and also fixes the userspace race where the device is created yet tools like libudev can not see the attributes as they think the subdirectories are some other sort of device.

pktdvd: stop using bdi congestion framework. The bdi congestion framework isn't widely used and should be deprecated. pktdvd makes use of it to track congestion, but this can be done entirely internally to pktdvd, so it doesn't need to use the framework. So introduce a "congested" flag. When waiting for bio_queue_size to drop, set this flag and a var_waitqueue() to wait for it. When bio_queue_size does drop and this flag is set, clear the flag and call wake_up_var(). We don't use a wait_var_event macro for the waiting as we need to set the flag and drop the spinlock before calling schedule() and while that is possible with __wait_var_event(), result is not easy to read.

[PATCH] pktcdvd: Allow larger packets The pktcdvd driver uses a compile time macro constant to define the maximum supported packet length. I changed this from 32 sectors to 128 sectors because that allows over 100 MB of additional usable space on a 700 MB cdrw, and increases throughput. Note that you need a modified cdrwtool program that can format a CDRW disc with larger packets to benefit from this change.

[PATCH] pktcdvd: Fix overflow for discs with large packets The pktcdvd driver was using an 8 bit field to store the packet length obtained from the disc track info. This causes it to overflow packet length values of 128KB or more. I changed the field to 32 bits to fix this. The pktcdvd driver defaulted to its maximum allowed packet length when it detected a 0 in the track info field. I changed this to fail the operation and refuse to access the media. This seems more sane than attempting to access it with a value that almost certainly will not work.

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!
