      remove blk_register_filter and blk_unregister_filter in gendisk · bb23b431
      FUJITA Tomonori authored
      This patch remove blk_register_filter and blk_unregister_filter in
      gendisk, and adds them to sd.c, sr.c. and ide-cd.c
      
      The commit abf54393 moved cmdfilter
      from gendisk to request_queue. It turned out that in some subsystems
      multiple gendisks share a single request_queue. So we get:
      
      Using physmap partition information
      Creating 3 MTD partitions on "physmap-flash":
      0x00000000-0x01c00000 : "User FS"
      0x01c00000-0x01c40000 : "booter"
      kobject (8511c410): tried to init an initialized object, something is seriously wrong.

      In the long term, we need to fix such subsystems but we need a quick
      fix now. This patch add the command filter support to only sd and sr
      though it might be useful for other SG_IO users (such as cciss).
