Subject: [PATCH v4 0/2] modules/kmod: replace implementation with a sempahore

Changes on this v4:

  o Really add Matthew Wilcox' preferred tribal knowledge docs
  o Add all the pending tags

Changes on v3:

  o Tons of spell checks thanks to Miroslav Benes
  o Fixed a stupid bug where I was using the timeout without HZ as
    reported by Miroslav Benes
  o Enanced the tribal knowledge docs for the semaphore Vs mutex
    considerations folks might make as suggested by Matthew Wilcox
  o Added tags for patches   

Changes on v2:                                                                                                                                                                                   
  o split the series up into its own
  o adopt Peter's patch and extend it with some documentation as to why
    some folks stick to binary semaphores over mutexes
  o modify kmod.c to use the preferred declaration
