[ros-diffs] [sginsberg] 43673: - Don't use KeBugCheck(0) -- 0 is an invalid bugcode. Use a proper bugcode, DbgBreakPoint or UNIMPLEMENTED instead depending on how the old call was used. - Remove some unused and deprecated macros from the network stack that did this. - fastfat_new: Use FAT_FILE_SYSTEM instead of magic 0x23.
