It was pretty abadonded in the last few years, so I did my best, but it's possible (given the charge and intensity of the magical field covering the whole kernel) that I still missed some of the magic numbers - so, if you will notice your favourite magic number missing there, please speak up. Note that I will probably make another update after few further kernel releases. Also, since some of the subsystems introduce fairly large amount of magic numbers, I placed simply references to the header files where the magic numbers are defined to the end of the file. I also made few tidyups (removal of tabs and reordering of few misplaced magics). I hope the patch is ok, there should be no problems with it. Please apply. magic-number.txt | 94 +++++++++++++++++++++++++++++++++++++++++++++---------- 1 files changed, 77 insertions(+), 17 deletions(-) Note that this is the fourth submission of the patch. There are no magic changes between 2.5.48 and 2.5.49, thus I only changed the kernel version and date.
