* tools/kcovtrace: add KCOV-based tracing utilityDmitry Vyukov2017-01-201-0/+62
kcovtrace is like strace but show kernel coverage collected with KCOV. It is very simplistic at this point and does not support multithreaded processes, etc. It can be used to understand, for example, exact location where kernel bails out with an error for a particular syscall.
