So what's the origin of the name
'strategy' for the I/O routine in Unix
that drivers provide? Everything I've found in the early papers just says
that's what the routine is called. Is there a story behind why it was
chosen? My own theory is that it's in the sense of 'coping strategy' when
the driver needs to service more I/O for the upper layers, but that's just
a WAG.
I always thought it had to do with computing the optimal strategy for
writing blocks to the disc device.... I wonder where I got that impression
from. Perhaps reading Bach?
