H A D | lock.h | 16edd9b5 Tue Mar 22 13:57:08 CDT 2022 Namhyung Kim <namhyung@kernel.org> locking: Add lock contention tracepoints
This adds two new lock contention tracepoints like below:
* lock:contention_begin * lock:contention_end
The lock:contention_begin takes a flags argument to classify locks. I found it useful to identify what kind of locks it's tracing like if it's spinning or sleeping, reader-writer lock, real-time, and per-cpu.
Move tracepoint definitions into mutex.c so that we can use them without lockdep.
