Although I have limited knowledge of Kernel technology in the specific, the C code, data structs, and programming concepts are spoon feed in this text and its wasting too much time with words that are more easily explained with coding examples and UML charts. I don't need a chapter explaining how to use ps and the basis of Unix architecture. This text is targeted to a different audience, and FWIW, I'm not certain it does a good job of that either. The guys who write these texts fall in love with their own voices. I know, I've suffered this disease myself when I've written tech articles and books. I can't recommend this book to anyone. Anyone who doesn't understand the basics of I/O processer blocks is not going to understand static void update_curr(struct cfs_rq *cfs_rq) and OTOH void update_curr(struct cfs_rq *cfs_rq) is not explained well enough for coders unfamiliar with the kernel data structs of which BTW struct cfs_rq is not well defined in the text. :( I'm looking for something more like this, but flushed out more as a textbook http://www.ibm.com/developerworks/library/l-completely-fair-scheduler/index.html, and some mentoring, I hope.
