Well, not quite yet but closer than it has been in the past!
The Definitive Guide to Linux System Calls.
From the post:
This blog post explains how Linux programs call functions in the Linux kernel.
It will outline several different methods of making systems calls, how to handcraft your own assembly to make system calls (examples included), kernel entry points into system calls, kernel exit points from system calls, glibc wrappers, bugs, and much, much more.
…
The only downside of the movement towards Linux is that its kernel, etc., will get much heavier scrutiny than in the past.
In the past, why bother with stronger code in a smaller market share?
Move Linux into a much larger market share, we may get to see if “…to many eyes all bugs are shallow.”
As an empirical matter, not just cant.
