Do you mean that if you type 'make modules' immediately after a previous
'make modules' completes, and in the interim you've not changed any
files, all of the modules still get rebuilt on your system?
What I've noticed (with versioned modules) is that when you update a file
that exports symbols, genksyms has to be re-run on that file, which in
turn updates modversions.h, which causes all modules from that point on
in the build sequence to be re-made. This can be inconvenient when you
modify a file that gets made early in the build sequence (e.g. serial.c)
as this can cause a _lot_ of modules to be rebuilt.
Looking forward to a modularized networking subsystem!
