SubjectRe: [PATCH] Replace completions with semaphores

i very much agree with the "get rid of semaphores" argument - the reason
why i initially supported the "move to generic semaphores" step was
because i saw it basically as the precursor to full removal: it is the
removal of semaphores from all architectures - with a small generic
compatibility wrapper to handle the remaining few uses of semaphores.

i got thoroughly surprised by the "increase the scope of semaphores"
angle to the patchset though, and in hindsight i'd rather see neither of
those generalizations and see semaphores die a slow but sure natural
death than to see their prolongation :-/

perhaps the 'remove all semaphores from all architectures' privilege
should be a final step kept for the lucky guy who manages to get rid of
the last remaining semaphore use in the kernel? :)
