Summary
Use the kernel tracer if you are debugging a system-wide performance problem or a kernel problem. This tracer comes with an instrumentation patch for most kernel subsystems, which is enough to debug many problems. This includes system calls, IRQs, traps, memory management, softIRQs, scheduling and many others. Of course, the kernel tracer allows you to add your own instrumentation anywhere in the kernel code.

proj/gentoo: Initial commit
This commit represents a new era for Gentoo: Storing the gentoo-x86 tree in Git, as converted from CVS. This commit is the start of the NEW history. Any historical data is intended to be grafted onto this point. Creation process: 1. Take final CVS checkout snapshot 2. Remove ALL ChangeLog* files 3. Transform all Manifests to thin 4. Remove empty Manifests 5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$ 5.1. Do not touch files with -kb/-ko keyword flags. Signed-off-by: Robin H.
