#     major.h: remove the remaining unnecessary includes of linux/major.h
#     
#     Now that very file that needs the definitions in major.h explicitly
#     includes it, this is just cleaning up.
#     
#     This is fairly safe because major.h does not include any other files.
#     The only real risk is if a symbol defined in major.h is constructed by
#     concatenation in the preprocessor.
#     
#     The actual change was done using the following command:
#     
#       sed -i -E '/[<"](uapi\/)?linux\/major\.h/d' \
#         $(grep -L -w -f xx \
#           $(git grep -E -l '[<"](uapi/)?linux/major\.h'))
#     
#     Where the file xx contians all the symbols defined in major.h
#     
#     (genhd.h was added by inspection.)
#     
#     The win here is really just the number of lines to be parsed by the
#     preprocessor.  major.h is 180 lines long and was being included by
#     these files unnecessarily.  In particular, there are 3 global include
#     files here (tty.h, genhd.h and blkdev.h) that are also included by 354,
#     68 and 554 other files, repectively.
#     
#     After this, major.h is only included by 4 global include files (which
#     are in turn included by 297 other files), so its indirect inclusion is
#     hopefully much reduced.
