This is the second group of patches which I'd like some review on as part of the *add_disk*() error handling conversion. While converting drivers to add error handling, I noticed some were using the flag GENHD_FL_UP to see if a block device is ready, or for bringing a device down, so to call del_gendisk() safely. This first group of patches just address the few areas where the flag is used directly. Direct use of the flag GENHD_FL_UP is useful but incorrect as we can add the flag in a gendisk left half built. Instead, add a flag to actually represent the desired goal. The next group will deal with the use of the flag for del_gendisk().
