Hi Gang Sorry upfront if the question is too trivial.. I am trying to understand syscalls by adding some debug statements in the code. Hardly elegent(I know). What I wanted to know was that do I need to do "make bzImage" every time after I touch even one of the file? There must be some quicker way. Pls also note that I am not fiddling with the modules and as such am not doing "make modules" and "make modules_install" afterwards.
