From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx> Subject: Documentation/kcov: include types.h in the example Patch series "kcov: PREEMPT_RT fixup + misc", v2. The last patch in series is follow-up to address the PREEMPT_RT issue within in kcov reported by Clark [1]. Patches 1-3 are smaller things that I noticed while staring at it. Patch 4 is small change which makes replacement in #5 simpler / more obvious. [1] https://lkml.kernel.org/r/20210809155909.333073de@xxxxxxxxxxx This patch (of 5): The first example code has includes at the top, the following two example share that part. The last example (remote coverage collection) requires the linux/types.h header file due its __aligned_u64 usage. Add the linux/types.h to the top most example and a comment that the header files from above are required as it is done in the second example.
